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.

 Input image not valid. Mandatory WCS keywords not found (CTYPEn, CRVALn, CRPIXn, etc)
 No REGION extension in the Region file. REGION extension does not contain valid column names (or the correct order): SHAPE, X, Y, R. Regions in the Source and Background region files have to be in the same coord. type.
 Source number of the Source and Background spectra differ.
 Plot device was not created for some reason.
 Cannot transform wcs coordinates to pixel coordinates. 'wcsfwd' error.
 At present the task only deals with MTYPE1 = "pos", CTYPE = "X/Y".
 X world pixel size and Y world pixel size differ.
corrective action: The input image array does not contain any WCS information. The displayed source positions may therefore be incorrect.
