PURPOSE: To return Electron Survey Data for a specific time from the fa_ees_l1 common block. USEAGE: dat=get_fa1_ees(t) dat=get_fa1_ees() will call ctime.pro to get t. The routine assumes the l1 common block for datatype is already loaded into IDL. KEYWORDS: /START to return data structure for the first time in common block. /EN to return data structure for the last time in common block. /ADVANCE to return the next data structure in the common block. /RETREAT to return the previous data structure in the common block. INDEX=INDEX to return the INDEXth data structure in the common block. /TIMES returns array of starting times in l1 common block instead of data structure. UNITS=UNITS allows you to choose the returned data's units. Default is compressed. UPDATES: Last update on June 4, 2010.
