     [ros=]  [cos=]  [-forceros]  [-reverse]  [-listonly]

   AUTOmatically IDentify arc-lines.  Looks in database
   for a previously calibrated arclamp with a similar setup.
 Options:
    id=file : ID file filename.  Default: (arc filename).ids .
   dbf=file : Explicitly specify one of the data base files of
              previously wavelength calibrated FITS files in
              $MAKEE_DIR/ArcLineDataBase/.  Default: guess.
    uf=file : Explicitly specify a user FITS file for the
              correlation instead of a data base file.
    ros=    : Guess row offset from DataBaseFile.
    cos=    : Guess column offset from DataBaseFile.
   -forceros: Force the program to use the "ros=" value.
   -clobber : Overwrite ID file if it exists.  Default: query.
   -verbose : Print lots of messages about line IDs.
   -soft    : Soften requirements for suitable database file.
    wll=    : Set Weak Line Limit (lines with peaks below this
              will be ignored.)  Default: 50.
   -nops    : Do not produce PS plots of correlation function
              (*-cf.ps) or final fit residuals (*-fr.ps).
   desat=   : Set saturated pixel level for desaturating
              columns which have bled due to strong Ar lines.
              Default: 60000.
     -nofit : Do not do final identifying and fitting.
  -fitonly1 : Only do final re-identifications and fitting.
  -fitonly2 : Only do final fitting.
  -reverse  : Reverse plot order (up,down,right,left).
  -listonly : Only show database file selection.
