STITCH /RESAMPLE

        LAS\STITCH [/RESAMPLE NX Xref Xval Xinc Unit]

    Without  this option, the X axis of the output sum will be automatically
    computed as the composition of all the input frequency axes. The  output
    spectrum  has  the  coarsest  resolution of the input spectra. Those are
    then internally resampled and added on this new axis.

    A custom output X axis can be given with the option  /RESAMPLE  NX  Xref
    Xval  Xinc Unit. The input spectra are internally resampled and added on
    this axis. See HELP RESAMPLE for possible uses and caveats.  The  output
    resolution  can  not be better than the coarsest resolution of the input
    spectra to avoid oversampling.
