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 event list file does not contain any exposure map extensions. The exposure map for at least one node is a required input. See task rgsfilter.
  The indicated region coverage parameter (xpsfincl, xpsfexcl, or pdistincl) was given a value greater than zero but less than one, suggesting that the user has forgotten that these parameters are specified as percentages.
corrective action: No corrective action is taken, but these regions will be too narrow to have any practical value. Specify zero to avoid this warning and get effectively the same result.
  A region selected for update is protected. Use a FITS editor to delete the region extension and then try again.
corrective action: The requested update of the region does not occur.
  A region has been produced which encloses no pixels in the channel space. This is most likely to occur with the spatial background region, particularly when more than one source is designated for exclusion.
corrective action: No corrective action is taken, but this warning should be taken seriously by the user, especially if the region in question is not the spatial background region.
