User-level errors and warnings

MissingDatawarning  odfingest cannot find some piece of information. This is not a problem for the users, but it may be a problem for the pipeline. For instance, if the PROPOSAL information record is missing the user can add a fake one to the SOSF without this having any effect on the data reduction.
corrective action: Continue.
 

HousekeepingParameterMissingwarning  For a certain exposure in the ODF one of the parameters was not found in the housekeeping data. This can be caused by:

• The time interval corresponding to the given exposure is not fully contained in the time span covered by the housekeeping data.
• The constraint above is met, but the further filtering of the housekeeping data with the filtering expression (see 3.4) yields an empty dataset.

corrective action: The parameter is ignored. A warning is written to the SOSF. For example: WARNING: FILTER_WHEEL not found __FILTER_WHEEL__ = 0
 

InconsistentDataModewarning  The task has encountered a situation where the same CCD appears to be in more than one data mode. This can point to one of the following:

• The central CCD of the EMOS camera is being readout of two nodes. This generates two separate files in the ODF, and these two files appear to have been taken with different configurations.
• Data from two different modes is found to be in the same exposure. For instance: PNU00201IME.FIT and PNU00201ODI.FIT are found in the same ODF.

The latter condition has actually been observed, although it is understood that it should not happen. If it does please report this to the XMM-Newton Science Operations Centre.
corrective action: All operations related to the determination of the CCD data mode, calibration mode, and instrument configuration will be disabled for the current exposure. In the summary file: MODE = UNDEFINED, and CALIBRATION_MODE and DATA_MODE entries are not present.
 

InconsistentCalibrationModewarning  The task has encountered a situation where the same CCD appears to be in more than one configuration. This is the configuration as expected by the cal.
corrective action: All operations related to the determination of the CCD data mode, calibration mode, and instrument configuration will be disabled for the current exposure. In the summary file: MODE = UNDEFINED, and CALIBRATION_MODE and DATA_MODE entries are not present.
 

NewHousekeepingValuewarning  One housekeeping parameter that was supposed to remain constant during the current exposure was instead found to have changed value. This may mean that the exposure start/stop times determined by odfingest are incorrect.
corrective action: The parameter is ignored. A warning is written in the SOSF. See the warning HousekeepingParameterMissing.
 

TranslationNotAvailablewarning  It is not possible to translate a housekeeping parameter value. For the developer. If the translator is a map {key,value}, this warning means that the translator does not contain a key corresponding to the parameter value. If the translator is a map {{min,max},value}, the warning indicates that the housekeeping parameter value is not contained in any of the available {min,max} ranges.
corrective action: Do not translate. A warning is written in the SOSF. See the warning HousekeepingParameterMissing.
 

UnknownInstrumentModewarning  It is not possible to determine the instrument mode from the list of available CCD calibration modes. This indicates one of the following:

• EMOS: the current exposure is found to contain more than two distinct calibration modes.
• EMOS: the current exposure does not contain a calibration mode entry for CCD 1.
• RGS, EPN, OM: the current exposure is found to contain more than one distinct calibration mode.

corrective action: In the summary file: MODE = UNDEFINED.
 

UnknownCalibrationModewarning  For the current exposure the Calibration Access Layer is unable to uniquely determine the calibration mode. In the summary file: MODE = UNDEFINED, and CALIBRATION_MODE and DATA_MODE entries are not present. This points to a problem in the data itself or in the CCF in use.
corrective action: All operations related to the determination of the CCD data mode, calibration mode, and instrument configuration will be disabled for the current exposure.
 

MissingOdfComponentwarning  The ODF component mentioned in the warning does not exist. This may prevent the SAS from processing the observation successfully.
corrective action: Ignore the problem. If the missing component is an housekeeping file the corresponding parameters will not be written to the SOSF.
 

InconsistentTimeRangewarning  The time range covered by the ODF constituent mentioned in the warning does not fully contain the observation span. Processing some of the exposures may fail because data are not available.
corrective action: None.
 

noOMExposurePairwarning  OM Exposure does not have correct EXP_START EXP_END pairs, using exposure time end for Actual End Time.
corrective action: None.
 

ZeroExposureLengthwarning  Detected a dataset with zero duration. This indicates that this exposure is unlikely to processable by the SAS.
corrective action: None.
 

NoOdfFounderror  The summary file is not written.
 odfingest did not find any ODF constituent in the directory pointed to by odfdir.

IncorrectNumberOfDatasetserror  The task expected to find one and only one ODF component matching a certain instrument/data mode pair. Both the file name pattern and the number of components found is reported.
 

InvalidRevolutionIdentifiererror  The revolution identifier of one of the ODF constituents found in the ODF directory is not an integer.
 

MultipleObservationserror  The ODF directory appears to contain ODF constituents belonging to more than one observation.
 

OdfSummaryFileNotFounderror  The ODF summary file matching the pattern *_SCX00000SUM.ASC was not found. This is part of every well-formed ODF.
 

MultipleObservationserror  ODF constituents from more that one ODF were identified in the ODF directory.
 

NotATimeSortedTableerror  The TIME of one of the housekeeping datasets is not sorted in ascending order.
 

FileIoerror  odfingest was unable to successfully write the summary file. Possible reasons: disk full, wrong permissions.
