;*NAME:		pmas_exp
;
;*CATEGORY:	PMAS instrument control
;
;*PURPOSE:	Start Spectrograph CCD exposure
;
;*CALLING SEQUENCE:
;
;*PARAMETERS:
;	INPUT:
;		t_exp
;	OUTPUT:
;		img                     resulting image (2D array)
;               fn                      file name of image on disk
;
;	KEYWORDS:
;		XBIN, YBIN:		x and y binning (1,2, or 3)
;		WIN=[x0,y0, xsize,ysize]  window readout parameters    		
;		OBJ= '...'		FITS header keyword (string)  
;		/NOWIPE			flag: suppress preceeding wipe cycle 
;		/TV or TV=scalefactor   automatic display on screen
;		RCP = '...'             <hostname:/path> for automatic remote copy
;		/QUICK                  quick start, no error checking'
;               /RET                    return immediately, no waiting for readout       
;               /LOG                    write to logfile
