LAS\AVERAGE [/NOMATCH] Average all the spectra of the current index using the current weighting function (see SET WEIGHT) and alignment mode (see SET ALIGN). The homo- geneity of calibration is checked according to SET CALIBRATION. Bad channels are handled according to SET BAD. A sum may be interrupted by <^C>, but the results is then undefined. The position coincidence of consecutive spectra will not be checked if option /NOMATCH is present. Else, this check relies on the current SET [NO]MATCH status. See SET MATCH to build an index with a given position- ing tolerance.
