IDENTIFY/MOS [wlc] [ystart] [linpos] [tol]
	interactive line identification in wavelength calibration frame
\us\pu
Purpose:   
	  Allows identification of wavelength calibration lines found 
	  by SEARCH/MOS
\up\sy
Syntax:
	  IDENT/MOS [wlc] [ystart] [linpos] [tol]
\ys\pa
	  wlc = Wavelength Calibration Frame
              Session keyword: WLC
              Default value: wlc
	  ystart = row in which lines shall be identified
              Session keyword: YSTART
              Default value: 0
	  linpos = table with line positions (pixels)
              Session keyword: LINPOS
              Default value: linpos
	  tol = tolerance window for line positioning
              Session keyword: TOLWIND
              Default value: 4

\as\no
Note:       
	  Uses the command IDENTIFY/GCURSOR to identify arc lines in a selected
          row of the calibration image. Pixel positions are stored in keyword
          XPOS and line identifications are stored in keyword LID.

Examples:
\ex
          IDEN/MOS wlc 148 linpos 3
          Searches table linpos.tbl whether row 148 has been searched. If not
          increases until a searched row is reached. Plots the row of wlc.bdf 
          and activates the command IDENTIFY/GCURSOR for identification. If you
          click a calibration line it searches within +/-3 pixels for a line
          listed in linpos.tbl. If it finds one, the pixel position is stored
          in keyword XPOS and you are asked for the identification, which is 
          stored in keyword LID.
