Errors

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.

.
emptyListerror 
 One of the source lists does not contain any data. (Can occur during processing of the data.)
 
emptySrcListerror 
 The data set with the X-ray source list is empty. (Input error.)
 
emptyCatListerror 
 The data set with the optical source list is empty. (Input error.)
 
invalidDecwarning 
 Apparently this source is very close to the equatorial pole and the RA is not well defined
corrective action: The value of RA_CORR for a particular source will be set to 0
 
noBmagnColumnwarning 
 The optical source list set does not contain a column with B magnitudes
corrective action: Ignore the B magnitudes, in case usebmagn was set to yes
 
noRmagnColumnwarning 
 The optical source list set does not contain a column with R magnitudes
corrective action: Ignore the R magnitudes, in case usermagn was set to yes
 
noRaDcPntwarning 
 The X-ray data set does not contain the RA_PNT and/or DEC_PNT keywords. As its values are used for the rotation, without these keywords no rotations can be found.
corrective action: Do not optimize for a rotational offset
 
invalidLikelihoodwarning 
 The value for the statistic used to optimize the offsets is too low, so that the solution may not be reliable.
corrective action: The corrective action is up to the user
 
NoUnitwarning 
 No RA unit; deg assumed
corrective action: Assume RA values are in degrees
 
NoUnitwarning 
 No DEC unit; deg assumed
corrective action: Assume DEC values are in degrees
 
NoUnitwarning 
 No error unit; arcsec assumed
corrective action: Assume errors are in arcsec
