ACCUMULATE /RESAMPLE
LAS\ACCUMULATE /RESAMPLE [NX Xref Xval Xinc Unit]
No /RESAMPLE
Without this option, a consistency test checks that R and T have
both the same X axes, according to the current SET ALIGN mode. If
yes, R and T are stacked channel by channel (no resampling). If not,
an error is raised and /RESAMPLE is suggested.
/RESAMPLE (without arguments)
The /RESAMPLE option is a request to allow the resampling, but it is
not enforced. A consistency test first checks if the spectra X axes
are identical or not, according to the current SET ALIGN mode. If
yes, R and T are stacked channel by channel (no resampling). If not,
the X axes are resampled according to the SET ALIGN mode. The X axis
of the output sum is automatically computed. In particular, the out-
put spectrum has the coarsest resolution of the two input spectra.
Those are then internally resampled and stacked on the output axis.
/RESAMPLE NX Xref Xval Xinc Unit
A custom output X axis can be given with the syntax /RESAMPLE NX
Xref Xval Xinc Unit. In this case, the resampling is always per-
formed. The input spectra are internally resampled and stacked on
this axis. See HELP RESAMPLE for possible uses and caveats.
Remember that if it is enabled, the resampling is time consuming and has
non trivial effects on the spectra noise.
