;NAME:
; thm_ui_only_trange
;PURPOSE:
; This program oprerates on the tplot data_quants to strip out data
; the is not in the input time range: start time, end time, and the
; subscripts of the appropriate data_quants structures are used, this
; is designed to be used in thm_ui_load_data_fn only... jmm,

;INPUT:
; st_time, en_time = time in seconds from 1-jan-1970 0:00
; data_ss = the subscripts of the data array to on which to operate
;OUTPUT:
; None explicit, the tplot variables are changed
;HISTORY:
; jmm, 13-nov-2006, jimm@ssl.berkeley.edu
; jmm, 13-dec-2006, made to work for non thg_mag data
