LAS\STITCH /NOCHECK [SOURCE|POSITION|LINE|SPECTROSCOPY|CALIBRA-
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).
