## THM_CRIB_GREENLAND_GMAG

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

    Procedure:
      thm_crib_greenland_gmag

    Purpose:
      Crib sheet demonstrating loading GMAG data from Greenland stations

    Notes:
      In addition to the NRSQ site included in the standard THEMIS GMAG
      data distribution, Jurgen Matzka(jrgm@space.dtu.dk) from the Technical
      University of Denmark has made data gmag data available from the DTU(previously DMI) and
      the TGO gmag networks.  Availability is 2007 through to the present.
      Although not all gmags are available at all times.
      To access these data, simply use the program thm_load_gmag
      More DMI data can be added upon request.  Otherwise, THEMIS archives will be updated
      approximately every 3 months.

      WARNING:  As with all GMAG data, users should be careful to verify data units
                and coordinate systems, as calibrations can drift from true values
                over time.  Users should be particularly careful with the older data
                from the DMI/DTU network. In particular, DMI/DTU data from the first
                part of 2009 and earlier is uncalibrated.

## THM_CRIB_MAKE_AE

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

    Procedure:
     thm_crib_make_ae

    Purpose:
     This is an example crib sheet that will calculate and plot "pseudo" geomagnetic
     indices (thmAE, thmAU, thmAL) as derived from THEMIS ground magnetometer data.
     In future, it is planned to include ground magnetometer data from other magnetometer
     networks. Note that currently the calculation of these "pseudo" indices does not
     subtract quiet day variation but simply the median.

     Open this file in a text editor and then use copy and paste to copy
     selected lines into an idl window.

    Notes:

    Notes:
      If you see any useful examples missing from these cribs, please let us know.
      A lot of instrument specific options (e.g. decontamination) are found in the other cribs.

    Notes on method:
      Internally, combined distributions are created in three steps:
        a) Linear time interpolation
             -time samples are matched by linearly interpolating the
              data set with lower time resolution to match the other
        b) Linear spherical interpolation
             -both data sets are interpolated onto the same angular grid
        c) Energy gap interpolation
             -once all times/angles match the gap between the
              ESA and SST energy ranges is filled in with a logarithmic
              linear interpolation (log(flux) vs log(energy))

## THM_CRIB_PART_COMBINE_NCOUNT

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

    Name:
      thm_crib_part_combine_ncount

    Purpose:
      Crib demonstrating how to subtract or mask a set number of counts
      from combined ESA-SST particle distributions.

      Rather than masking/subtracting the raw data this will create
      a second product in parallel: a mask that can be applied to the
      final product (i.e. the subtraction is applied after averaging
      and/or interpolating the data instead of before)

       The underlying routine - spd_pgs_export - will create 5 ASCII files:
         [filename]_data.txt: the velocity distribution data
         [filename]_energy.txt: the energy values at each bin
         [filename]_theta.txt: the theta values at each bin
         [filename]_phi.txt: the phi values at each bin
         [filename]_bins.txt: 1 or 0 depending on if this bin is active

       If no filename is specified, dist.project, dist.spacecraft and dist.data_name are used to form the filename

## THM_CRIB_RECOVERY_VXY_MOM_EARLY_2007[1]

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

    Name:
      thm_crib_recovery_Vxy_mom_early_2007

    Purpose:
      This command gets the onboard moments, which are wrong because of an
      error in uploading the onboard tables.

      Correlation likely depends on temperature, so the same coefficients
       may not be applicable to the entire day.  In these cases it may be
       necessary to narrow the interval (intervals of 1/3 day is probably
       about right).  The variables ii and nn mark the start and stop of
       the interval calculated, so adjust those to find appropriate time
       periods.  Adjust the sc and timespan lines to change spacecraft and
       days. Also, the moment data end up being a bit noisy, so you may
       want to run 'avg_data', with a small timestep (maybe 10 seconds or so).
       th?_v?_corr contains the high resolution velocity, and th?_v?_dec
       contains the data decimated to match the low resolution data, for
       comparison.

## THM_CRIB_SPINFIT

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

    Procedure:
      thm_crib_spinfit

    Purpose:
      Demonstration of finding spin fit parameters for spinning data.
      The FIT module calculates the E-Field and B-Field vectors by taking 32 points at equal angles
      and fitting a sine wave least squares fit to the data. The best fit of the data is defined by the
      formula: A + B*cos() + C*sin(). The module calculates the standard deviation of the fit
      called Sigma, and the number of points remaining in the curve called N.

    Usage documentation for thm_spinfit

        Arguments:
          required parameters:
            var_name_in = tplot variable name containing data to fit

        Keywords:
           sigma = If set, will cause program to output tplot variable with sigma for each period.
           npoints = If set, will cause program to output tplot variable with number of points in fit.
           spinaxis = If set, program will output a tplot variable storing the average over the spin axis dimension
                    for each time period.
           median  = If spinaxis set, program will output a median of each period instead of the average.
           plane_dim = Tells program which dimension to treat as the plane. 0=x, 1=y, 2=z. Default 0.
           axis_dim = Tells program which dimension contains axis to average over. Default 0.  Will not
                    create a tplot variable unless used with /spinaxis.
           min_points = Minimum number of points to fit.  Default = 5.
           alpha = A parameter for finding fits.  Points outside of sigma*(alpha + beta*i)
                 will be thrown out.  Default 1.4.
           beta = A parameter for finding fits.  See above.  Default = 0.4
           phase_mask_starts = Time to start masking data.  Default = 0
           phase_mask_ends = Time to stop masking data.  Default = -1
           sun2sensor = Tells how much to rotate data to align with sun sensor.

       Notes:
        	 The module determines which data is more than xN * �N (sN = standard deviation) away from fit,
           and removes those points and repeats the fit. The second time the standard deviation is
           smaller so the tolerance is increased a bit. The tolerance xN varies with try as:
           Alpha*NBeta, where A=1.4 and Beta=0.4 provide good results. The operation continues
           until no points are outside the bounds and the process is considered convergent.

             Wave power: On a linear scale (units of nT^2/Hz if input Bx, By, Bz are in nT)

             Degree of Polarisation:
    		This is similar to a measure of coherency between the input
    		signals, however unlike coherency it is invariant under
    		coordinate transformation and can detect pure state waves
    		which may exist in one channel only.100% indicates a pure
    		state wave. Less than 70% indicates noise. For more
    		information see J. C. Samson and J. V. Olson 'Some comments
    		on the description of the polarization states
    		of waves' Geophys. J. R. Astr. Soc. (1980) v61 115-130

             Wavenormal Angle:
    		the angle between the direction of minimum
    		variance calculated from the complex off diagonal
    		elements of the spectral matrix and the Z direction
    		of the input
    		ac field data. For magnetic field data in
    		field aligned coordinates this is the
    		wavenormal angle assuming a plane wave.

             Ellipticity:The ratio (minor axis)/(major axis) of the
    		ellipse transcribed by the field variations of the
    		components transverse to the Z direction. The sign
    		indicates the direction of rotation of the field vector in
      		the plane. Negative signs refer to left-handed
    		rotation about the Z direction. In the field
    		aligned coordinate system these signs refer to
    		plasma waves of left and right handed
    		polarisation.

             Helicity:Similar to Ellipticity except defined in terms of the
    	direction of minimum variance instead of Z. Stricltly the Helicity
    	is defined in terms of the wavenormal direction or k.
    	However since from single point observations the
    	sense of k cannot be determined,  helicity here is
    	simply the ratio of the minor to major axis transverse to the
           minimum variance direction without sign.
