;
;*CATEGORY:            PMAS instrument control software
;
;*PURPOSE:             start 'dark' exposure
;
;*CALLING SEQUENCE:    pics_s_dark ,err,sec, WAIT=0/1, WIPE=0/1
;
;*PARAMETERS
;             input:   expt   optional: exposure time in seconds (float),
;                             fraction of second is allowed
;
;            output:   err    error variable (string), ''= no error
;
;          Keywords:   /WAIT  wait for completion, return after file is

;                             Works only if WAIT=1
;
;		       XBIN=  x bin factor (1,2, or 3)
;                      YBIN=  y bin factor (1,2, or 3)
;                      Note:  BIN keywords are optional; if not present use
;                             previous setting as stored in epics database
;
;		       WIN=   [ X0,Y0, XSIZE,YSIZE ] window readout parameters.    		
;                             If WIN is not set, the full CCD will be read out.
;                             If /WIN is set, default win parameters are used
;                      RCP = '...'   <hostname:/path> for automatic remote copy
