ACCUMULATE /NOCHECK
LAS\ACCUMULATE /NOCHECK [SOURCE|POSITION|LINE|SPECTROSCOPY|CALIBRA-
TION|SWITCHING]
By default, ACCUMULATE checks the consistency between R and T. 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! ACCUMULATE 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:
ACCUMULATE /NOCHECK SPECTROSCOPY
will assume R and T are aligned and will stack them channel by chan-
nel (no resampling), while they are possibly not aligned.
ACCUMULATE /RESAMPLE /NOCHECK SPECTROSCOPY
will assume R and T are not aligned and will always resample them
before stacking, even if not necessary (adds computation cost and
possible round off errors).
