STITCH /NOCHECK

            LAS\STITCH    /NOCHECK   [SOURCE|POSITION|LINE|SPECTROSCOPY|CALIBRA-
        TION|SWITCHING]

        By default, STITCH checks the consistency between all the input spectra.
        This  is a security to avoid mixing inconsistent data (e.g. spectra from
        different sources). These checks can be individually (with one  or  more
        names) or all (no name) disabled using the option /NOCHECK. See HELP SET
        NOCHECK for details.

        Note the key status of the SPECTROSCOPY check! STITCH uses this check to
        detect if the spectra frequency axes are aligned or not, to help its de-
        cision to enable resampling  or  not  (see  /RESAMPLE  subtopic).  Using
        /NOCHECK SPECTROSCOPY enforces the spectra alignment status:

        STITCH /NOCHECK SPECTROSCOPY
            will  assume  the spectra are aligned and will stack them channel by
            channel (no resampling), while they are possibly not aligned.

        STITCH /RESAMPLE /NOCHECK SPECTROSCOPY
            will assume the spectra are not aligned  and  will  always  resample
            them  before  stacking, even if not necessary (adds computation cost
            and possible round off errors).
