STITCH

        LAS\STITCH  [/RESAMPLE  NX  Xref Xval Xinc Unit] [/NOCHECK [Arg1 ...
    ArgN]] [/IMAGE] [/WEIGHT TIME|SIGMA|EQUAL|ASSOCIATED]

    Stitch (i.e. make the union of) all the spectra of the current index us-
    ing  the  specified (/WEIGHT) or current (SET WEIGHT) weighting function
    (see HELP SET WEIGHT for details). The command behaves like AVERAGE /RE-
    SAMPLE  except  it ignores the SET ALIGN status and composes the spectra
    on the signal frequency axis. Use the option /IMAGE to compose  them  on
    the image frequency axis.

    On  return  the  R spectrum contains the average spectrum. If /WEIGHT or
    SET WEIGHT is ASSOCIATED (see HELP SET WEIGHT for details),  the  weight
    array of the average spectrum is saved in the associated array named W.

    Bad  channels are handled according to SET BAD. A sum may be interrupted
    by <^C>, but the result is then undefined.
