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).
