SSample run of maskgenx using file C0210.galaxies.in.0
mulchaey@hercules> maskgenx
 Enter input filename:
C0210.galaxies.in.0
 Enter a title (<=32 chars.) for the mask plot:
C0210.galaxies.in.0
Enter RA (hms) and Dec (dms) of input center on one line
02 10 24.89 -39 29 37.1
Enter Epoch
2000
 Enter 1 to skip warning if alignment star out of field
 Enter 0 to give warning
0
 Enter 99 to modify default parameters, otherwize 0
99
 Is this mask for COSMIC ? 
no
 Enter 1 to change alignment star box size
 Enter 0 to accept default size [8.0 arc sec]
0
 Enter 1 to change normal polarity convention, 0 to accept default
 default is E is positive, N is positive
0
 Enter 1 if input scale in pixels (not arcsec)
 AND input *NOT* from WFCCD direct image; else 0
0
 Enter number of lines to skip at top of input file:
2
 Enter 0 to bypass automatic offset changes, else 1
0
 Enter 0 to set priorities automatically
 (alignment star squares are always selected)
0
 Enter 1 to modify default field size limits, else 0
 default values are 1500 arcs along slits [x] and
 1080 arcs along dispersion direction [y]
0
Enter 0 for slits (default), 1 for holes
0
Enter 1 to modify slit separation, slit end-to-object and
minimum slit length
Enter 0 to accept defaults (4.0 pix, 2.0 arcsec, 10.0 arcsec)
4,2,15
Are tilted slits required? (requires individual P.A.s in 6th column of input)
no
Do you wish to stack spectra?
no
 Enter the CASS RING angle for your observations
 acceptable angles are 90.0 < ringangle <= 270.0
 180 gives N/S slits; 270 recommended for E/W slits
270
 Enter the global slitwidth in arcsec

 Type <RETURN> for next page:
 Enter 1 to change the rotation angle and re-select objects
      2 to exclude an object,
      3 to include an object,
      4 to plot again on the terminal,
      5 type current list to term/outputfile,
      6 to write a photomask.ps file   
      7 to edit lengths of slits
      8 to include all objects
      9 to exclude all objects
      10 to add overall offset in x or y to all slits and reselect:
      11 to exit program, no further output:
