This section documents warnings and errors generated by this task (if any). Note that warnings and errors can also be generated in the SAS infrastructure libraries, in which case they would not be documented here. Refer to the index of all errors and warnings available in the HTML version of the SAS documentation.

 The input units for ranges have been set to keV but a redistribution matrix hasn't been supplied.
 Only one statistical method, e.g. minimum counts, minimum S/N or ratio above background, can be specified
 The ranges must be entered as '1-10' or '1:10' if specified in channels or as '2.0:4.53' or '2.0-4.53' if specified in keV.
 The specified energy range is outside the range of energies contained in the spectrum
 The start bin for regular binning must be >= 0
 The template spectrum has a different number of channels from spectrum to be grouped.
 There has been a clash between the ranges and regular binning requested.
 A bin which has been requested to be set bad by the setbad option has already been grouped and so will stay as a good channel.
corrective action: leave channel as good
 After grouping has completed and ungrouped channels are treated according to the lastbin parameter selection. Sometimes it is impossible to find a contiguous group to add a given channel to. Contiguous channels which fall in this category are used to form a new group.
corrective action: create a new group
