; Name        : NEXPOSURES()
;               
; Purpose     : Return the number of "exposures" in a QLDS
;               
; Explanation : Returns the number of exposures, defined as the
;		size of the larger of the DEL_TIME and the SSOLAR_X
;		dimensions.
;               
; Use         : NEXP = NEXPOSURES(QLDS)

; Common      : None.
;

; Prev. Hist. : Used to be called nraster, but change of terminology
;		(RASTER -> EXPOSURE) prompted name change.
