## MMS_BSS_LOAD

[Next Routine] [List of Routines]

     NAME: mms_bss_load

     PURPOSE: To return burst-segment status (aka 'back-structure')
              within a given time interval. Ask super-SITLs for the meaning of
              each tag in the returned structure.

     CALLING SEQUENCE: result = mms_bss_load(trange)

     INPUTS:  trange .... can be either string or double

     EXAMPLE:

         MMS> tr = time_double('2015-11-04/'+['04:00','05:00'])
         MMS> s = mms_bss_load(trange=tr)
         MMS> help, s

     NOTES:

         1. If no burst-segment were found within the trange, then this function returns -1

         2. The timerange 'trange' should not be too big (like more than a month).
            because LaTis (at SDC) will return an erratic result (as of 2016-09-02).

         3. The FIN keyword is obsolete and should not be used if the above issue (item 2)
            remains.

       FIN: Set this keyword to find segments that 'finished' within trange
            instead of querying segments that were defined within trange.
            Because a segment can take many tens of days,
            trange is expand to [tlaunch,tnow] when retrieving segment info.

## MMS_BSS_QUERY

[Previous Routine] [List of Routines]

     NAME: mms_bss_query

     PURPOSE:
         To query the back-structure. Somehow, the SDC code "get_mms_burst_segment_status"
         does not work well for querying by status. Here, the program loads the entire
         set of the back-structure (or you can limit it by 'trange') and then analyze
         the segments.
