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.

NoOdfComponenterror 
 odffix could not find any dataset resembling an ODF component.
 
InvalidRevolutionIdentifiererror 
 odffix found a possible ODF dataset with a revolution identifier that is not a positive integer. Most likely the revolution identifier is an alphanumeric string. This is not compliant with the ODF Interface Control Document, and is known to cause problems in some parts of the SAS.
 
UnknowOdfFileTypeerror 
 odffix could not convert the name of the file to a known ODF file type.
 
InvalidFilterNameerror 
 odffix Filter name found in the AUX files is not correct.
 
DefaultPointingwarning 
 odffix could find a wayt to extract the pointing information from the ODF.
corrective action: Use a default pointing. Use ra and dec to specify the pointing information.
 
MultipleODFwarning 
 Files belonging to more than one ODF were found in the directory.
corrective action: Ignore ODF components that belong to a different ODF.
 
missingAttributewarning 
 odffix could not one attribute in the dataset. Usually this is a DATE-XXX attribute.
corrective action: odffix ignores the problem and tries its best to find a correct date to assign to the ODF. The ODF components without valid DATE-XXX attributes are still listed in the ODF summary file. Thisis not a problem when using ODF components generated with scisim, as they always contain the appropriate date attributes. When using odffix on ``home brewn'' ODF components the user should check that the generated files make sense, i.e. they contain sensible DATE-OBS and DATE-END attributes. If this is not the case, the individual ODF components should be edited to contain DATE-OBS and DATE-END.
 
NegativeDurationwarning 
 The observation duration appears to be less than $0s$. Something may be wrong with the DATE-XXX attributes read from the ODF constituents.
corrective action: Continue, but the resulting ODF summary file may be invalid.
 
DefaultDurationwarning 
 No meaningful DATE-XXX pair was found in any of the data sets. This can cause odffix to exit with an out of memory error, as it tries to allocate an inordinate amount of memory for the time correlation file. To prevent this from happening, when sucha condition is detected the duration of the observation is hardcoded to be 3600 s.
corrective action: Continue. The observation start date is set to now, and the observation duration is set to 3600 s.
 
LongObservationwarning 
 The calculated observation duration is excessively long (value indicated). This may indicate a problem with the DATE-XXX attributes from the ODF components, and also leads to the generation of very large files by odffix.
corrective action: None.
 
AttitudeHistoryFileExistswarning 
 odffix has detected a pre-existing attitude history file.
corrective action: Because the pre-existing file could have been generated by scisim, a new attitude history file will not be created.
 
OMTrackingHistoryDataFileExistswarning 
 odffix has detected a pre-existing OM tracking history data file.
corrective action: Because the pre-existing file could have been generated by the SOC PMS system, a new file will not be created.
 
OMPriorityWindowDataFileExistswarning 
 odffix has detected a pre-existing OM priority window data file.
corrective action: Because the pre-existing file could have been generated by the SOC PMS system, a new file will not be created.
 
invalidDateStringwarning 
 A dataset contains a date string that cannot be interpreted.
corrective action: The dataset is not used to calculate the observation duration and start/stop time.
