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 expression for this spatial region was not valid.
 The centre of the source or background region lies outside of the image
 The image is not two dimensional.
 The image axes specified in the CTYPE1 and CTYPE2 keywords are not compatible.
 If the spectrum contains an observing mode (in the keyword SUBMODE) which is not recognised then the software assumes that that the common PrimeFullWindow mode was in use. The mode is used to calculate certain calibration quantities.
 If the INSTRUME keyword is not set in the image header a warning is issued and the default of MOS-1 is taken. The instrument determines the PSF used and the position of the optical-axis.
 The REFerence keywords in the image header, e.g. REFXCRPX, REFXCRVL, REFXCDLT are incomplete. Defaults are chosen but there is likely to be a problem later.
 The psfmodel has not been set to ELLBETA. This means that the optimum elliptical extraction region will not be properly calculated.
