AVERAGE /NEW

        LAS\AVERAGE /NEW [/NOMATCH] [/RESAMPLE [NX Xref Xval Xinc Unit]]

    Average all the spectra of the current index using the current weighting
    function (see SET WEIGHT). The spectra are added channel by  channel  by
    default,  if  possible.  Else  the option /RESAMPLE must be invoked (see
    subtopic for details).

    The homogeneity 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 result 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.

    AVERAGE  also works on Continuum drift. The alignement may be Channel or
    Position in this case.
