AVERAGE /NOCHECK

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

    By  default,  AVERAGE  checks  the consistency of 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! AVERAGE uses this check
    to detect if the spectra X axes are aligned or not, to help its decision
    to  enable  resampling  or  not (see /RESAMPLE subtopic). Using /NOCHECK
    SPECTROSCOPY enforces the spectra alignment status:

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

    AVERAGE /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).
