;PROCEDURE:	load_sta_l1_sweamom
;PURPOSE:	
;   loads STEREO/IMPACT SWEA moments high resolution data for "tplot".
;
;INPUTS:	none, but will call "timespan" if time
;		range is not already set.
;KEYWORDS:
;  TIME_RANGE:  2 element vector specifying the time range
;  DATA:        Data returned in this named variable.
;  NODATA:	Returns 0 if data exists for time range, otherwise returns 1.
;  PREFIX:	(string) prefix for tplot variables.  Default is 'sta_'
;  NAME:	(string) name for tplot variables. Default is 'sta_let'
;  MASTERFILE:	(string) full filename of master file.
;SEE ALSO: 
;  "make_cdf_index","loadcdf","loadcdfstr","loadallcdf"
