## THM_SST_ATTEN_SCALE

[Previous Routine] [Next Routine] [List of Routines]

    NAME:
     thm_sst_atten_scale
    PURPOSE:

     This routine determines the appropriate attenuator scale factor array based on the SST angle mode and
     the attenuator flags

    Inputs:
      atten_flags: 4-bit flag indicating which attenuators are engaged
      data_dims: The return value of dimen(data.data)

    Keywords:
      scale_factors(optional): 4-element array with the scaling factors for each attenuator pinhole.
                               Defaults to 1./64.

    Returns:
      Scaling factor array

    SEE ALSO:
      thm_sst_convert_units

    NOTES:
    atten_flags are a 4-bit value for the attenuator flags
    Defined as MSB,Open Equatorial Attenuator,Closed Equatorial Attenuator,Open Polar Attenuator,Closed Polar Attenuator, LSB
    With MSB/LSB not representing actual bits, but as labels to clarify bit order.
    Some examples:
     0x5: both attenuators closed
     0xA: both attenuators open
     0x6: equatorial closed, polar open  (Occurs during stuck atten error on themis D)
     0xf: Error state. Invalid data.
     0x9: equatorial open, polar closed (This should never actually happen)

    Under normal circumstances both attenuators are in the same state and the open/closed flags are mutually exclusive.

## THM_SST_ERANGE_BIN_VAL

[Previous Routine] [Next Routine] [List of Routines]

    PROCEDURE: THM_SST_ERANGE_BIN_VAL

    Purpose:
       This routine generates the values that will be subtracted to remove electronic noise.  The actual subtraction is done by thm_sst_remove_sunpulse.pro
       A separate value will be calculated for each combination of bin and energy, but a single value will be calculated for all times(at a particular bin/energy).
       This value will be generated using one of several different functions of the values across time.  The functions can be specified by the user.
       The user should never call this routine directly, but should instead provide the appropriate arguments to thm_part_moments,thm_part_moments2, & thm_part_getspec
       These routines will guarantee that this routine is called correctly.

    Arguments(note these arguments are generated correctly in thm_part_moments & thm_part_moments2)
       thx:  a string representing a probe prefix(ie 'tha')

       instrument:  a string representing the instrument(ie 'psif')  Note that this routine will only perform an operation if
       it is passed a string representing sst full distribution data.  (ie 'psif', 'psef')

       times:  a list of times for the sst measurements, this list is generated by thm_part_dist

    Keywords:

     method_clean: If set to 'manual', this keyword disables the enoise code, as another method will be used by thm_sst_remove_sunpulse.pro

     enoise_bins:  A 0-1 array that indicates which bins should be used to calculate electronic noise.  A 0 indicates that the
                   bin should be used for electronic noise calculations.  This is basically the output from the bins argument of edit3dbins.
                   It should have dimensions 16x4.

     enoise_bgnd_times:  This should be either a 2 element array or a 2xN element array(where n is the number of elements in enoise_bins).
                        The arguments represents the start and end times over which the electronic background will be calculated for each
                        bin.  If you pass a 2 element array the same start and end times can be used for each bin.  If you pass a 2xN element
                        array, then the Ith bin in enoise_bins will use the time enoise_bgnd_time[0,I] as the start time and enoise_bgnd_time[1,I] as
                        the end time for the calculation of the background for that bin.  If this keyword is not set then electronic noise will not
                        be subtracted.

     enoise_remove_method(default: 'fit_median') set the keyword to a string specifying the method you want to use to calculate the electronic noise that will be subtracted
                          This function combines values across time.  The allowable options are:
                          'min':  Use the minimum value in the time interval for each bin/energy combination.
                          'average': Use the average value in the time interval for each bin/energy combination.
                          'median': Use the median value in the time interval for each bin/energy combination.
                          'fit_average': Fill in selected bins with a value that is interpolated across phi then subtracts the average of the difference
                          between the interpolated value and the actual value from each selected bin/energy combination.
                          'fit_median' :Fill in selected bins with a value that is interpolated across phi then subtracts the median of the difference
                          between the interpolated value and the actual value from each selected bin/energy combination.
                          'fill':  Fill the selected bins using the technique specified by enoise_remove_method_fit, or interpolation by default. (note that if this method is used, enoise_bgnd_time is not required)

     enoise_remove_fit_method(default:'interpolation'):  Set this keyword to control the method used in 'fit_average' & 'fit_median' to
                        fit across phi. Options are 'interpolation' & 'spin_fit' By default, missing bins are interpolated across phi.  Setting
                        enoise_remove_fit_method='spin_fit' will instead try to fill by fitting to a curve of the form A+B*sin(phi)+C*cos(phi).

## THM_SST_FIND_MASKING

[Previous Routine] [Next Routine] [List of Routines]

    PROCEDURE: THM_SST_FIND_MASKING
    Purpose:
      This routine is designed to find the indices of the masking in the SST Full distribution data.
      It directly checks the common block and then returns it for use by the remove_sunpulse routine
      While it is the function that actually takes the mask_fill argument, it should not ever be
      directly called by a user.   It was written so that it can identify the mask locations
      efficiently using a total, prior to the point at which thm_part_moments and thm_part_moments2
      begin to iterate over time.

      The majority of the documentation can be found in thm_remove_sunpulse.pro and thm_crib_sst_contamination.pro

     Arguments:
        thx:  a string storing the satellite prefix(ie 'tha')
        instrument:  a string identifying the instrument(ie 'psif')
        index:  a list of indices which specify the times that were requested
     Keywords:
        mask_remove: Set this keyword to the proportion of values that must be 0 at all energies to determine that a mask is present.
                 Generally .99 or 1.0 is a good value.   The mask is a set of points that are set to 0 on-board the spacecraft.  By default they will
                 be filled by linear interpolation across phi.  This keyword should be passed down via _extra from the parent
                 routine.  If this keyword is not set, this routine will always return -1.

## THM_SST_REMOVE_SUNPULSE

[Previous Routine] [Next Routine] [List of Routines]

    PROCEDURE: THM_SST_REMOVE_SUNPULSE
    Purpose:
      Routine to perform a variety of calibrations on full distribution sst data.
      These can remove sun contamination and on-board masking. They can also scale
      the data to account for the loss of solid angle from the inability of the sst
      to measure directly along the probe geometric Z axis and the inability to measure
      directly along the probe geometric xy plane.(ie X=0,Y=0,Z = n or X=n,Y=m,Z=0,  are SST 'blind spots')
      THM_REMOVE_SUNPULSE routine should not generally be called directly.
      Keywords to it will be passed down from higher level routines such as, thm_part_moments,
      thm_part_moments2, thm_part_dist,thm_part_getspec, thm_sst_psif, and thm_sst_psef

      Arguments:
               dat:  the dat structure used in thm_part_dist, etc...

      Keywords:

      method_clean: Simplified sun cleaning methods:
                       Allowed options are:
                       'manual': To use this option you need to specify the contaminated bins using the sun_bins keyword.  Specified bins are removed and interpolated over phi.

                       'automatic': This method attempts to find contaminated bins using a statistical outlier test(modified z-score)
                        then fills the bins by interpolation over phi.

      sun_bins: method_clean manual removal bin selection.  Must be either a 64 element or a 16x64 element 0-1 array.  Bins set to 1 will be used, bins set to 0
                      will be removed and filled.
                      The 64 element input is the same format as the output from edit3dbins, it removes and fills all energies at a particular angle of measure.
                      The 16x64 element input allows the user to remove some bins at some of the 16 energies but to keep others.

      all_angle_median:  set this option to replace the angular distribution with the median
                         of the data calculated over the all angles(thetas & phis) for each energy.
                         This will generally eliminate contamination in some of the moments, but will make
                         analysis of angular plots impossible. It will also eliminate the velocity
                         moment.
      scale_sphere:  set this option to increase the value of all counts by 16%.  This accounts
                     for the loss of phase space mentioned above.

      method_sunpulse_clean:  set this to a string:  Either 'median' or 'spin_fit' or 'z_score_mod'
                  'median':  This will remove all points that are greater
                    than 2.0 standard deviations from the median.By default they will be filled by a
                    linear interpolation across the phi angle by default.
                  'spin_fit':  This will remove all points that are greater
                    than 2.0 standard deviations from a spin fit across phi angle.  The equation used to
                    fit is A+B*sin(phi)+C*cos(phi). By default these points will be filled by a linear
                    interpolation across the phi angle. The fitting is done using the svdfit routine
                    from the idl distribution.
                  'z_score_mod': This will remove all points that have a modified z-score(calculated across phi) greater than 3.5
                    The modified z-score is a normalized outlier detection test defined as follows:
                    #1 X_Bar = median(X+1)
                    #2 Sigma = MAD = Median Absolute Deviation = median(abs(X-X_Bar))
                    #3 Z_Score_Mod = .6745*(X - X_Bar)/Sigma
                    This test can often get excellent results because it is insensitive to variation in standard deviation
                    and skew in the distributions.

      limit_sunpulse_clean: set this equal to a floating point number that will override the default of 2.0 standard
                 deviation tolerance or 3.5 z_score_tolerance, used by the sunpulse cleaning methods by default.
                 This keyword will only have an effect if the method_sunpulse_clean keyword is set.

      fillin_method: Set this keyword to a string that specifies the method used to fill the points that are
                 removed via the method_sunpulse_clean or the mask_remove keywords, and bins removed when enoise_remove_method='fill'.
                 'interpolation': this routine will interpolate across the phi angle.  This is the
                   default behavior. Interpolation is done using the interp_gap routine.
                 'spin_fit': this routine will perform a spin fit to the data after the points
                   have been removed using the equation A+B*sin(phi)+C*cos(phi).  It will then generate
                   expected values for each removed phi using the equation of fit.   The fitting is done using
                   the svdfit routine from the idl distribution.  Note that if 'spin_fit' is selected for
                   the clean method and the fill method, this routine will perform two spin fits.
                 'blank' : Just removes the data but doesn't fill with anything

      mask_remove: Set this keyword to the proportion of values that must be 0 at all energies to determine that a mask is present.
                 Generally .99 or 1.0 is a good value.  The mask is a set of points that are set to 0 on-board the spacecraft.
                 By default they will be filled by linear interpolation across phi.  NOTE: This argument is not actually accepted by
                 this routine, it is only documented here.  If you provide this argument to thm_part_moments,
                 thm_part_moments2, or thm_part_getspec, those routines will appropriately set the value for the
                 mask_tot keyword to this routine.

     enoise_bins:  A 0-1 array that indicates which bins should be used to calculate electronic noise.  A 0 indicates that the
                   bin should be used for electronic noise calculations.  This is basically the output from the bins argument of edit3dbins.
                   It should have dimensions 16x4. NOTE: This argument is not actually accepted by
                   this routine, it is only documented here.  If you provide this argument to thm_part_moments,
                   thm_part_moments2, or thm_part_getspec, those routines will appropriately set the value for the
                   enoise_tot keyword to this routine.

     enoise_bgnd_time:  This should be either a 2 element array or a 2xN element array(where n is the number of elements in enoise_bins).
                    The arguments represents the start and end times over which the electronic background will be calculated for each
                    bin.  If you pass a 2 element array the same start and end times can be used for each bin.  If you pass a 2xN element
                    array, then the Ith bin in enoise_bins will use the time enoise_bgnd_time[0,I] as the start time and enoise_bgnd_time[1,I] as
                    the end time for the calculation of the background for that bin.  If this keyword is not set then electronic noise will not
                    be subtracted.NOTE: This argument is not actually accepted by
                    this routine, it is only documented here.  If you provide this argument to thm_part_moments,
                    thm_part_moments2, or thm_part_getspec, those routines will appropriately set the value for the
                    enoise_tot keyword to this routine.

     enoise_remove_method(default: 'fit_median') set the keyword to a string specifying the method you want to use to calculate the electronic noise that will be subtracted
                    This function combines values across time.  The allowable options are:
                    'min':  Use the minimum value in the time interval for each bin/energy combination.

                    'average': Use the average value in the time interval for each bin/energy combination.

                    'median': Use the median value in the time interval for each bin/energy combination.

                    'fit_average': Fill in selected bins with a value that is interpolated across phi,  then use
                         the average of these values across the time interval for each bin/energy combination.

                    'fit_median' : Fill in selected bins with a value that is interpolated across phi,  then use
                         the mean of these values across the time interval for each bin/energy combination.

                    'fill': Fill in selected bins across phi, do not perform any subtraction.  This will
                    provide the cleanest looking plot, but the signal in that bin will be entirely removed.

                      NOTE: This argument is not actually accepted by
                         this routine, it is only documented here.  If you provide this argument to thm_part_moments,
                         thm_part_moments2, or thm_part_getspec, those routines will appropriately set the value for the
                         enoise_tot keyword to this routine.

      enoise_remove_fit_method(default:'interpolation'):  Set this keyword to control the method used in 'fit_average' & 'fit_median' to
                        fit across phi.
                        Options are:
                        'interpolation'
                        'spin_fit'
                        By default, missing bins are interpolated across phi.  Setting
                        enoise_remove_fit_method='spin_fit' will instead try to fill by fitting to a curve of the form A+B*sin(phi)+C*cos(phi).

      mask_tot:  The user should never manually set this keyword.  thm_part_moments,thm_part_moments2, & thm_part_getspec
                 will properly set this keyword, if the mask_remove keyword is set when they are called.

      enoise_tot: The user should never manually set this keyword. thm_part_moments,thm_part_moments2, & thm_part_getspec
                 will properly set this keyword, if enoise keywords are set when called.
