     Each variable may have a different set of attributes, but this
     example is a minimal structure that will be ISTP compliant.

     KEYWORDS:
       VARFORMAT = string or string array:  a string or string array (which may contain wildcard
                             characters) that specifies the CDF variable names to load.  Use
                              'VARFORMAT='*' to load all variables. NOTE
                              THAT VARFORMAT MUST BE SET IF YOU ACTUALLY
                              WANT TO READ DATA.
       VARNAMES = named variable   ;output variable for variable names that were loaded.
       SPDF_DEPENDENCIES :   Set to 1 to have SPDF defined dependent variables also loaded.
       VAR_TYPE = string or string array;  Variables that have a VAR_TYPE matching these strings will
                             be loaded.
       CONVERT_INT1_TO_INT2  Set this keyword to convert signed one byte to signed 2 byte integers.
                             This is useful because IDL does not have the equivalent of INT1   (bytes are unsigned)
       RECORD: Specify the record index where you want to start reading.  By default, this option will read one record.
       NUMBER_RECORDS: Specify the number of records that you want to read.  By default, this option will begin at record zero.

     Note: Record & Number_Records can be used together to specify a range of records to be read.

     Side Effects:
       Data is returned in pointer variables. Calling routine is responsible for freeing up heap memory - otherwise a memory leak will occur.

## CDF_SAVE_VARS2

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

     Version of CDF_SAVE_VARS with some fixes, square brackets. Hopefully
     temporary, need to reconcile with data_dimen issues in CDF_SAVE_VARS

     FUNCTION: dummy = cdf_save_vars(cdf_structure,new_cdf_name)
     PURPOSE:  To dump data and metadata from an IDL structure into a CDF file.
    		The structure format is the structure produced by cdf_load_vars.pro
     INPUTS:   cdf_structure : IDL structure defined by cdf_load_vars.pro
    	    new_cdf_name  : a string to name the new CDF file with
     OUTPUTS:  CDF file named by the new_cdf_name input

     KEYWORDS: SET_COMPRESSION
     Set this keyword to the compression type to be used for the
     single-file CDF file. Note that individual CDF variables may use
     compression types different than the one for the rest of the CDF
     file. Valid compression types are:
        0 = No Compression
        1 = Run-Length Encoding
        2 = Huffman
        3 = Adaptive Huffman
        5 = GZIP (see the optional GZIP_LEVEL keyword)
     SET_GZIP_LEVEL
     This keyword is used to indicate the desired effort for the GZIP
     compression. This effort must be expressed as a scalar in the range
     (1-9). If GZIP_LEVEL is not specified upon entry then the default
     effort level is taken to be 5. If the SET_GZIP_LEVEL keyword is set
     to a valid value, and the keyword SET_COMPRESSION is not specified,
     the SET_COMPRESSION is set to GZIP (5).

     EXAMPLE:  dummy = cdf_save_vars(cdfi,'newcdf.cdf')

     Written by: Matt Davis

    Note: To use this routine you must have the CDF_EPOCH/CDF_EPOCH16 bug patch on your IDL6.3
    and if you are using Solaris you need to be in 32-bit mode NOT 64-bit
    (ie, idl -32)

## DUMMY_MAVEN_L2_STRUCT

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

    unction dummy_maven_l2_struct, vars, only_1_time_array = only_1_time_array, $
                                   instrument = instrument, _extra=_extra
     Takes an array of tplot variables, creates a dummy CDF master
     structure, inserts data, returns structure suitable for output.
     If you set the only_1_time_array keyword, then there will be only 1
     time_array, the instrument keyword also needs to be set, so that the
     time variable name is 'instrument_time' (e.g., instrument = 'swe_l2'
     will give a time variable name of 'swe_l2_time'. Otherwise, the time
     variable name will be 'L2_time').

## MVN_CALL_SWE_L2GEN

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

    NAME:
     mvn_call_swe_l2gen
    CALLING SEQUENCE:
     mvn_call_swe_l2gen
    INPUT:
     None -- the default is to read in a file
             /disks/data/maven/data/sci/swe/l2/most_recent_l0_processed.txt
             and process all files after that time
    KEYWORDS:
     time_in = the time for which old files created *after* this date
               will be processed. E.g., if you pass in '2017-11-07'
               then all files created after 7-nov-2017/00:00:00 will
               be reprocessed
     before_time = if set, process all of the files created *before* the
                  input time
     days_in = An array of dates, e.g., ['2009-01-30','2009-02-01'] to
               process. This ignores the input time. This option
               replicates the proceesing done by
               thm_reprocess_l2gen_days.
     out_dir = the directory in which you write the data, default defined
               by the MAVEN directory structure, e.g.:
                   '/disks/data/maven/data/sci/swe/l2/YYYY/MM/'
     use_file4time = if set, use filenames for time test instead of file
                     modified time, useful for reprocessing
     search_time_range = if set, then use this time range to find files
                         to be processed, instead of just before or after
                         time.
     use_l2_files = if set, then use L2 files as input, and not
                    L0's. Note that L0 is still used for file
                    searching, so you might want to use this with the
                    days_in option. (passed through to mvn_swe_l2gen.pro)
     l2only = if set, then insist on using L2 MAG data for generating
              L2 PAD data
     no_reset_time = if set, then don't reset the time in
                     most_recent_l0_processed.txt (useful for repocessing
                     data without affecting the cron job)
     max_l0_files = This is the maximum number of L0 files that can be
                    processed, the deault is 30. This is a fail-safe to
                    avoid mass reprocessing of data, if a bunch of file
                    ctime values are inadvertently changed. If more files
                    than this limit are tried, an error email will be sent.
     allbad = if set, mark all data as affected by the low-energy anomaly.
              Permanently set to zero.  This will never be done again.
     refresh = action to take if quality save file is not found: 0 = do nothing,
               1 = create only if missing, 2 = create/overwrite any existing file
               Default = 2, because muser is processing the latest data, and the
               coverage can change with each revision.
     kp_comp = controls processing of spacecraft potentials when calculating key
               parameters.  0 = ignore composite potential and use the SWE+ method,
               1=try to use the composite potential first; if that fails use the
               SWE+ method.  Default = 1.
     mail_xtra = send emails to this address as well as to the default address

     function_in is an IDL main program (LEAVE OUT THE .pro)
     THis function needs to run on inputs read in from start and end time files.
     nproc is the number of processes that are desired
     time_range is a 2xN array of start and end times,
     proc_workdir is the directory where the function_in program lives,
     each subprocess will create a directory, copy the function_in
     program into that directory, and run it there. The function_in
     program must pick up its start_time from a file
     'function_in_start_time.txt' in that directory, and not work
     past 'function_in_end_time.txt'. These files are created for the
     first process, and the start_time file gets updated each time the
     program runs.

     be generic_multiprocess_b.sh
     Changed name, removed the SSW calls, for use for overplotting. Note
     also that this version overwrites start and end times if the
     subdirectories exist, jmm, 21-nov-2011
     Added offset to be able to use multiple computers, jmm, 6-oct-2013

       DATE:      If set, the input date. The default is today.

       DIRECTORY: If set, output into this directory, for testing
                   purposes, don't forget a slash '/'  at the end.

       L2ONLY:    If set, only generate PAD L2 data if MAG L2 data are available.

       NOL2:      If set, do not generate SWEA L2 data.  Takes precedence over the
                  next three keywords.

       DOSPEC:    Process the SPEC data.  Default = 1 (yes).

       DOPAD:     Process the PAD data.  Default = 1 (yes).

       DO3D:      Process the 3D data.  Default = 1 (yes).

       DOKP:      Process the KP data.  Default = 1 (yes).

       MASK_SC:   Mask the spacecraft blockage.  This is in addition to any
                  masking defined by the ABINS, DBINS, and OBINS.
                  Default = 1 (yes).  Set this to 0 to disable and use the
                  above 3 keywords only (not recommended!).

       KP_QLEV:   Minimum quality level for calculating key parameters.  Filters out
                  the vast majority of spectra affected by the sporadic low energy
                  anomaly below 28 eV.  The validity levels are:

                    0B = Data are affected by the low-energy anomaly.  There
                         are significant systematic errors below 28 eV.
                    1B = Unknown because: (1) the variability is too large to
                         confidently identify anomalous spectra, as in the
                         sheath, or (2) secondary electrons mask the anomaly,
                         as in the sheath just downstream of the bow shock.
                    2B = Data are not affected by the low-energy anomaly.
                         Caveat: There is increased noise around 23 eV, even
                         for "good" spectra.

                  Default for this procedure is 1B.

       KP_COMP:   Value for COMPOSITE keyword for mvn_swe_kp.

       HIRES:     Use the constant flux method for identifing the hires sweep
                  tables (7-9).  Only needed during hires campaigns.

       REFRESH:   Action to take if a quality save file is not found.
                  This keyword can have one of three integer values:

                    0 : Do nothing.  Just fill the quality flag array
                        with 1's (unknown) for all times covered by the
                        missing file.

                    1 : Attempt to create the missing file, then try to
                        load it.

                    2 : Create or recreate all files, overwriting any
                        existing file(s).  Default.

                  *** This keyword only works for authorized users! ***

## MVN_SWE_QUALITY_DAILY

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

    PROCEDURE:   mvn_swe_quality_daily
    PURPOSE:
      Calculates the quality flag for the low-energy suppression anomaly.
      Quality flag data are stored in daily IDL save/restore files.

      Quality flag definitions:

          0B = Data are affected by the low-energy anomaly.  There
               are significant systematic errors below 28 eV.
          1B = Unknown because: (1) the variability is too large to
               confidently identify anomalous spectra, as in the
               sheath, or (2) secondary electrons mask the anomaly,
               as in the sheath just downstream of the bow shock.
          2B = Data are not affected by the low-energy anomaly.
               Caveat: There is increased noise around 23 eV, even
               for "good" spectra.

    USAGE:
      mvn_swe_quality_daily, trange

    INPUTS:
           trange:       One or more dates, in any format accepted by time_double.
                         Only full UT days are processed; any fractional part of
                         the day is ignored.  When trange has more than one element,
                         all days between the earliest and the latest (inclusive)
                         are processed.

    KEYWORDS:
           NOLOAD:       Do not initialize SPICE and do not load data.  Assumes that
                         these steps are performed before calling this routine.
