; setup some variables for the device command:
; ----------------------------------------------------------------------
   filename = 'filename.ps'   ; or change to *.eps for encapsulated

   encapsulate = 1            ; set to 1 for EPS files to include in documents
                              ; set to 0 for PS files that can be printed by themselves


; issue device setting commands:
; ----------------------------------------------------------------------
   set_plot, 'ps'
   device, file=filename, $
           encap=encapsulate

; to manually set the output dimensions (only recommended for EPS files), 
; you can add these parameters to the device command:

;          /inch, xsize=9, ysize=5

; (if you just leave these off, the output usually looks fine)



; system variable settings:
; ----------------------------------------------------------------------
   !p.font=0                  ; set to 0 for postscript fonts
   !p.charsize=1.2            ; enlarge text slightly

; when you make your xtitle/ytitle strings, use !3 to set all the following 
; text to helvetica, !9 for symbol:

   !x.title='!3Wavelength (!9m!3m)'





; (your plot commands would go somewhere here)




; finish:
; ----------------------------------------------------------------------
   device, /close
   set_plot, 'x'
