## THM_LOAD_SST2

[Next Routine] [List of Routines]

    Procedure: thm_load_sst2

    Purpose:  Loads THEMIS SST data

    WARNING: This routine is under development as part of the SST calibration process. Use at your own risk!

    keywords:
      probe = Probe name. The default is 'all', i.e., load all available probes.
              This can be an array of strings, e.g., ['a', 'b'] or a
              single string delimited by spaces, e.g., 'a b'
      datatype = The type of data to be loaded, for this case, there is only
              one option, the default value of 'sst', so this is a
              placeholder should there be more that one data type. 'all'
              can be passed in also, to get all variables.
      TRANGE= (Optional) Time range of interest  (2 element array), if
              this is not set, the default is to prompt the user. Note
              that if the input time range is not a full day, a full
              day's data is loaded
      level = the level of the data, the default is 'l1', or level-1
              data. A string (e.g., 'l2') or an integer can be used. 'all'
              can be passed in also, to get all levels.
      CDF_DATA: named variable in which to return cdf data structure: only works
              for a single spacecraft and datafile name.
      VARNAMES: names of variables to load from cdf: default is all.
      /GET_SUPPORT_DATA: load support_data variables as well as data variables
                          into tplot variables.
      /DOWNLOADONLY: download file but don't read it.
      /valid_names, if set, then this routine will return the valid probe, datatype
              and/or level options in named variables supplied as
              arguments to the corresponding keywords.
      files   named varible for output of pathnames of local files.
      /VERBOSE  set to output some useful info
    Example:
       thg_load_sst,/get_suppport_data,probe=['a', 'b']

    Notes:

      Many of the standard keywords only work with L2 data.

      When L1 data is loaded it is merged into a data structures stored
      in tplot variables named: th?_ps??_data.

      These structures have the form:
       X               DOUBLE    Array[27797]
       Y               INT       Array[27797]
       MDISTDAT        STRUCT    -> <Anonymous> Array[1]

       X is the time array for the data
       Y is the index to the distribution type that is valid at each time.
       D.Y will index MDISTDAT.DISTPTRS, although not all distptrs are guaranteed to be valid.(ie Not all distributions will be used in a given data set)

      This modification replaces use of data_cache and common blocks for passing sst data between routines.

## THM_PART_DIST2

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

    NAME:
     thm_part_dist2
    PURPOSE:
     wrapper function around the different routines called 'get_p???'
     used for ESA particle data and 'thm_sst_p???' routines that extract
     SST data.

     This is a working version for development of SST calibrations.
    INPUT:
     format = a string denoting the data that is desired: options are:
              'tha_peif': Full Esa mode data, ions, probe A
              'tha_peef': Full Esa mode data, electrons, probe A
              'tha_peir': Reduced Esa mode data, ions, probe A
              'tha_peer': Reduced Esa mode data, electrons, probe A
              'tha_peir': Burst Esa mode data, ions, probe A
              'tha_peer': Reduced Esa mode data, electrons, probe A
              'tha_psif': Full Sst mode data, ions, probe A
              'tha_psef': Full Sst mode data, electrons, probe A
              'tha_psir': Reduced Sst mode data, ions, probe A
              'tha_pser': Reduced Sst mode data, electrons, probe A
             For other probes, just replace 'tha' with the appropriate
             string, 'thb', 'thc', 'thd', 'the'
              If this is not set, then the string is constructed from the
              type and probe keywords
     time = an input time, if not passed in, then this routine will
            attempt to get the time from plotted data, via ctime, unless
            the index keyword is passed in (for SST) or
            when start, en, advance, retreat, or index are passed in.
    KEYWORDS:
     type = 4 character string denoting the type of data that you need,
            e.g., 'peif' for full mode esa data
     probe = the THEMIS probe, 'a','b','c','d','e'
     cursor = if set, then choose a time from the plot, using
              ctime.pro. This overrides any input -- that is, the
              variable that was used becomes the input variable and the
              time obtained becomes the time of the data.
     index = an index for the data point that is to be returned
     start (ESA only) = if set, then get the first saved data point
     en (ESA only) = if set, get the last saved data point
     advance (ESA only) = if set, get the data point after the one that
                          was gotten last
     retreat (ESA only) = if set, get the data point before the one that
                          was gotten last
     times = if set, returns the time array for all the saved data points
     skip_sst_att_correct = if set skip correction for effective
                            attenuation, which is done by default if the
                            variables 'th?_ps?f_ratio_var' exist for the
                            given probe and species.
    OUTPUT:
     dat = the '3d data structure' for the given data type: In general
           this will be different for different data types, but there are
           elements that are common to all, Here is a sample for tha_psif
           data:

## THM_SST_ATT_CORRECT

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

    NAME:
     thm_sst_att_correct
    PURPOSE:
     tests for attenuator transition, calculates background level and
     correction factor, and corrects the attenuation level in the saved
     data structures. Ideally the correction is interpolated between two
     attenuator transistions.
    CALLING SEQUENCE:
     thm_sst_att_correct, probe, date, dur = dur
    INPUT:
     probe = 'a', 'b', 'c', 'd', or 'e'
     date = start date
    KEYWORDS:
     dur = duration in days, note that some attenuator intervals are more
           than a day, if there is no attenuator transition during the
           date input, no correction will be calculated. If there is only
           one transition in the data, then the correction will not be
           interpolated over the full interval.
     auto_extend = If duration is 1 day, the auto_extend option will
                   extend the calculation to previous and later days if
                   the attenuators are in at the start and end of the
                   day. This will extend at least 7 days in either
                   direction.
    NOTES:
    Uses thm_part_dist2, and not thx_sst_psi?f

## THM_SST_CONVERT_UNITS2

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

    NAME:
     thm_sst_convert_units2
    PURPOSE:

      This routine converts input data into the desired physical units
      It is used as a callback function by ssl_general routines like moments_3d/conv_units
      It will mutate the contents of the struct that is passed as an argument.

    Inputs:
      data: data struct that is being converted, this structure will have its data mutated
      units: string identifying the desired output units
      other_data: Proper calibration of the SST requires removal of ion & electron cross-contamination at high energies.  If this argument contains the associated struct from
      the opposite species, cross contamination will be removed.

    Outputs:
      scale: scale factor that was used to convert the data into the desired format, should have dimensions that match the data

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

    NAME:
     thm_sst_dist3d_16x64
    PURPOSE:
      This routine returns the appropriate distribution representation struct for
      16 Energy and 64 angle SST data.(16 energy by 4 theta by 16 phi)
      Default and/or constant values will be populated.  At this point,
      the structure should be considered incomplete.

## THM_SST_ENERGY_CAL2

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

    NAME:
     thm_sst_energy_cal2
    PURPOSE:
      This routine performs bin energy boundary calibrations.  Transforming DAP values into eV
      The routine directly modifies the dat struct according to parameters stored in the struct
      But results can be returned for reference.

    Inputs:
      dat

    Outputs:
      energy:  The midpoint of each energy bin
      denergy: The width of each energy bin

## THM_SST_READ_CALIBRATION_PARAMS

[Previous Routine] [List of Routines]

    NAME:
     thm_sst_read_calibration_params
    PURPOSE:
      This routine reads calibration parameters from a file.

    Inputs:
      thx:  probe identifier string (e.g. 'tha','thb'...)
      species: 'e' or 'i', to indicate ion or electron
      dtype: distribution type 'f','b','r'

    Returns:
      The parameter struct for the calibration file

    NOTES:
      #1 Reading and applying the calibration parameters is done separately, because reading later when
         they are applied leads to duplicated parameter reads. And because there is not enough information
         to apply parameters at load time.
