## EXECUTE_LATIS_QUERY

[Next Routine] [List of Routines]

     Execute the given query and return the results in an array of
     structures of the given type.
     This may return an error code or -1 if no data are found.

(See projects/mms/sdc/execute_latis_query.pro)

## GET_MMS_SROIS

[Previous Routine] [List of Routines]

     Query a LaTiS web service to get the SROIs whose
     start_time falls within the given time range.
     SROIs include predicted (future) values, which are subject to change.

     start_time and end_time arguments are optional. If specified, they
     must be UTC dates or datetimes in a format similar to the following:
       2020-02-15/08:21:01.000
     The '/' can optionally be a space or 'T'.
     The time part can be omitted. Fractional seconds are optional.
     If neither argument is specified, SROIs for all times are returned.
     Comparison to start_time is inclusive (>=), to end_time is exclusive (<).

     sc_id is optional. If omitted, results are returned for all spacecraft.
     Otherwise, it must be one of 'mms1', 'mms2', 'mms3', 'mms4', case-insensitive.

     Normally returns an array of struct with the following fields derived
     from the mms_events_view LaTiS dataset.

     start_time : string, UTC datetime string, e.g., '2020-02-15/08:21:01.000'
     end_time   : string, UTC datetime string
     sc_id      : string, 'mms1', etc.
     orbit      : int, MMS orbit number at start_time_utc
     public     : bool, if set, executes the latis query as a public user

     The array is always sorted by start_time ascending.

     Can return an integer error code or -1 if no data are found.

     Example:
     IDL> srois = get_mms_srois(start_time='2020-02-15/08:21:01.000', sc_id='mms1')
     IDL> help,srois
     SROIS           STRUCT    = -> SROI Array[60]
     IDL> help,srois[0]
     ** Structure SROI, 4 tags, length=56, data length=52:
     START_TIME      STRING    '2020-02-15/08:21:01.000'
     END_TIME        STRING    '2020-02-15/17:54:03.000'
     SC_ID           STRING    'mms1'
     ORBIT           LONG              1084
