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.

filesNonCompatibleerror 
 Input files are non-compatible (file type, DATAMODE)
 
differentObservationserror 
 Two input event files from different observations have been used. This is strongly discouraged because of the subsequent difficulty of accurately using downstream software on the merged event file. Experts can force the task to merge these files by setting the command line parameter mergedifferentobs="yes"
 
MergeGeneralWarningwarning 
 Merged eventsets may result in incorrect results of some downstream tasks
corrective action: See the task description!
 
filesNonCompatiblewarning 
 Input files not entirely compatible (INSTRUME, FILTER)
corrective action: Input files are merged - care should be taken as to subsequent use
 
noExposureMergewarning 
 Input files are from different instruments - EXPOSURE extensions not merged
corrective action: Different instrument Exposure extensions not merged
 
noGTIMergewarning 
 Input files are from different instruments - GTI extensions not merged
corrective action: Different instrument GTI extensions not merged
 
largePointingOffsetwarning 
 Pointings are offset by a significantly large amount
corrective action: Reprojection is performed - care should be taken as to subsequent use
 
noExtensionwarning 
  extension does not exist in one or both files - not merging
corrective action: Particular extension is not merged into output file
 
noTimeColumnwarning 
 TIME column missing in one file - cannot establish order
corrective action: Files are merged in the user-input order
 
noColumnwarning 
  Column `Column name' missing in one file - not merging
corrective action: Particular column is not merged into output file
 
noXYColumnswarning 
  X and/or Y columns do not exist in one or both input files - no reprojecting
corrective action: Coordinate reprojection is not performed
 
fileTimeOverlapwarning 
 Files overlap in time - some TIME keywords cannot be correctly calculated
corrective action: Calculation of some keywords not performed - ONTIME, LIVETIME etc
 
tooManyColumnswarning 
 Too many columns given on command line
corrective action: Only first 12 user-specified columns will be copied
 
unMatchedGTIwarning 
 Flare GTI extension missing in one dataset: will result in incorrect exposure times!
corrective action: Create matching input datasets and rerun task
 
unMatchedSTDGTIwarning 
 STDGTI extension missing in one dataset: will result in incorrect exposure times!
corrective action: Create matching input datasets and rerun task
