AVERAGE /RESAMPLE
LAS\AVERAGE /RESAMPLE [NX Xref Xval Xinc Unit]
Without this option, all the spectra will be added channel by channel. A
consistency test will check that they both have the same X axes. SET
ALIGN values are ignored in this case. Prefer this solution when possi-
ble, since it is faster and safer.
With the /RESAMPLE option, the X axis of the output sum will be automat-
ically computed according to the alignment mode (SET ALIGN). In particu-
lar, the output spectrum has the coarsest resolution of the input spec-
tra. Those are then internally resampled and added on this new axis.
A custom output X axis can be given with the syntax /RESAMPLE NX Xref
Xval Xinc Unit. The input spectra are internally resampled and added on
this axis. See HELP RESAMPLE for possible uses and caveats. The output
resolution can not be better than the coarsest resolution of the input
spectra to avoid oversampling.
Remember that if it is enabled, the resampling is time consuming and has
non trivial effects on the spectra noise.
