Procedure: elf_load_options Purpose: Provides information on valid data rates, levels, and datatypes for ELFIN science instruments. Valid load options for a specified instrument will be returned via a corresponding keyword. Each output keyword may be used as an input to narrow the results the the contingent options. Calling Sequence: elf_load_options, instrument=instrument [,rate=rate] [,level=level], [,datatype=datatype] [valid=valid] Example Usage: Input: instrument: (string) Instrument designation, e.g. 'afg' rate: (string)(array) Data rate e.g. 'fast', 'srvy' level: (string)(array) Data processing level e.g. 'l1b', 'ql' datatype: (string)(array) Data type, e.g. 'moments' Output: rate: If not used as an input this will contain all valid rates for the instrument. level: If not used as an input this will contain all valid levels, given any specified rate. datatype: If not used as an input this will contain all valid datatypes, given any specified rate and level. valid: 1 if valid outputs were found, 0 otherwise Notes: $LastChangedBy: egrimes $ $LastChangedDate: 2016-09-22 12:22:45 -0700 (Thu, 22 Sep 2016) $ $LastChangedRevision: 21901 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/elfin/elf_load_options.pro $

Purpose: Extracts valid rate/level/datatype based on input. If an input is specified then only subsets of that input are checked. If an input is not specified then all possible matches are used. e.g. -If rate is specified then only levels and datatypes for that rate are retuned. -If nothing is specified then all rates/levels/datatypes are returned. -If all three are specified then then the output will be identical to the input (if the input is valid).
