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.

paramErrorerror 
 A minimum wavelet scale was requested, larger than the maximum wavelet scale
 
inputImErrorerror 
 The task encountered a serious error when trying to read the input image.
 
inputMapErrorerror 
 The task encountered a serious error when trying to read the input exposure map.
 
reconErrorerror 
 The task encountered problems making a model image, containing Gaussians for all detected sources. This map is used to subtract sources from the input image in order to generate a better background image.
 
bgdCalcerror 
 Error generating background map.
 
wavCalcerror 
 Wavelet analysis error. Should be accompanied by warnings, which give more specific information.
 
srclistErrorerror 
 Error generating final source list. No sources may have been found.
 
unsupportedDataTypewarning 
 
corrective action: The task uses single floating point arrays to store images, doubles are automatically changed to single floating point values, but this may cause errors.
 
noExpMapwarning 
 In some cases an exposure map may not be available, this is, however, not recommended and will result in this warning.
corrective action: A flat exposure map is made, using the EXPOSURE keyword of the input image
 
noMatchwarning 
 One of the following keywords in the input image/exposure map did not match: OBS_ID,EXP_ID and/or INSTRUMENT.
 
reconErrorwarning 
 This will usually mean that the source list is empty, so that a "reconstructed image" could not be made
corrective action: No reconstructed image will be written/or in some cases a proper background map cannot be made, which generates an error.
 
diffCoordwarning 
 World coordinates of two images (e.g. exposure map and input image) are different
 
noSourceswarning 
 No source are present in the source list.
 
coordErrorwarning 
 Signifies an error in the image world coordinates system.
corrective action: The columns RA and DEC will remain empty in the final source list
