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.

Please see the selectlib documentation for information on errors and warnings having to do with event selection and filtering. Please see the dsslib documentation for information on errors and warnings having to do with the data subspace.

 A spectrum with a non-standard PATTERN or PI range has been requested which is incompatible with the matrix generation tasks. This may be overridden by setting the parameter nonStandardSpec=true.
 
NotXmmSpectrumwarning 
 The input data set was not recognized as an XMM data set. A weighted rate spectrum can only be produced for XMM data.
corrective action: A spectrum file is not produced.
 
NoAttribwarning 
 The Attribute does not exist in the input event list. No value was copied.
corrective action: No value for the given attribute is copied into the product file.
 
MinParamRangewarning 
 Value of parameter outside allowed range for column. Setting to minimum value.
corrective action: The minimum value used for product extraction is set to the minimum allowed value.

 Value of parameter outside allowed range for column. Setting to maximum value.
corrective action: The maximum value used for product extraction is set to the maximum allowed value.
 
MaxDataRangewarning

BadHistoLimitserror 
 The column used for histogram extraction has its upper limit less than its lower limit.
 
HistoColumnNamewarning 
 The input column for accumulating a histogram is called COUNTS, which causes a name clash in the histogram output file.
corrective action: The X axis column in the histogram file is renamed to OLD_COUNTS.
 
XlimitEpsilonwarning 
 X axis upper limit adjusted by an epsilon amount. This is to guarentee that all events which fall into the range of the image get accumulated.
corrective action: X axis upper limit adjusted by an epsilon amount.
 
YlimitEpsilonwarning 
 Y axis upper limit adjusted by an epsilon amount. This is to guarentee that all events which fall into the range of the image get accumulated.

BadImgLimitswarning 
 One of the columns used for image extraction has its upper limit less than or equal to its lower limit, or the column has the same value throughout.

NoWCSwarning 
 No WCS information is available for an image column.
corrective action: Pixel based WCS information is written to the output image.
 
BinVsFrameTimewarning 
 Time bin size is less than the mean frame readout time.
corrective action: No action taken.
 
RateEnergywarning 
 A data subspace energy filter has been found which cannot be incorporated into the calculation of E_MIN and E_MAX values for a rate curve. E_MIN and E_MAX values may be incorrect.
corrective action: Energy filter is ignored.
 
BadRateLimitswarning 
 The column used for light curve extraction has its upper limit equal to its lower limit, or the column has the same value throughout.
corrective action: An empty light curve is created.
 
BadRateLimitserror 
 The column used for light curve extraction has its upper limit less than its lower limit

 The column used for spectral extraction has its upper limit equal to its lower limit, or the column has the same value throughout.
corrective action: An empty spectrum file is created.
 
BadSpecLimitserror 
 The column used for spectral extraction has its upper limit less than its lower limit
 
NotXMMwarning 
 Can only update exposure information on XMM data. No updating of exposure information is performed.
corrective action: Exposure information is not updated.
 
RgsTimeFilterwarning 
 You have used the TIME column to filter an RGS events list. This will invalidate any exposure information in the produced products.
corrective action: Execution continues.
 
NoTargetOntimewarning 
 The ONTIMEnn attribute for the target CCD could not be found in the event list. The global ONTIME will be set to zero.
corrective action: ONTIME is set to zero.
 
NoTargetLivetimewarning 
 The LIVETInn attribute for the target CCD could not be found in the event list. The global LIVETIME will be set to zero.
corrective action: LIVETIME is set to zero.
 
ExpMultiCcdFilterswarning 
 A data subspace component was found which contains more than one CCDNR filter, ie more than one expression specifying which CCD events should be selected from. The exposure correction code is not designed to handle this, I will in most cases produce wrong results when updating exposure information. Usually having more than one CCDNR filter in a component results in the exposure time (on time) not being uniform for all events in the CCD.
corrective action: Execution continues
 
ExpBadCcdTypewarning 
 The CCDNR column was used in a filtering expression for which it cannot be guaranteed that the selection criteria will result in a uniform exposure time (on time) for each CCD. This part of the filtering expression is thus ignored in the updating of the exposure information.
corrective action: Filter ignored in updating of exposure information
 
ExpBadCcdCompwarning 
 The CCDNR column was used in a filtering expression for which it cannot be guaranteed that the selection criteria will result in a uniform exposure time (on time) for each CCD. This part of the filtering expression is thus ignored in the updating of the exposure information.
corrective action: Filter ignored in updating of exposure information
 
ExpBadTimeTypewarning 
 The TIME column was used in a filtering expression for which it cannot be guaranteed that the selection criteria will result in a uniform exposure time (on time) for each CCD. This part of the filtering expression is thus ignored in the updating of the exposure information.
corrective action: Filter ignored in updating of exposure information
 
ExpBadTimeCompwarning 
 The TIME column was used in a filtering expression for which it cannot be guaranteed that the selection criteria will result in a uniform exposure time (on time) for each CCD. This part of the filtering expression is thus ignored in the updating of the exposure information.
corrective action: Filter ignored in updating of exposure information
 
ExpBadGlobalCompwarning 
 The filtering expression used may not result in a uniform exposure time (on time) to be applied to all events for a given CCD. This is because the expression applies one time criteria to one set of events, and another time criteria to a different set of events.
corrective action: Execution continues
 
NotXmmProductwarning 
 Not XMM data. Cannot calculate EXPOSURE keyword for output products.
corrective action: Exposure calculation aborted. Execution continues.
 
NoProductExpwarning 
 No live time information available. Cannot write EXPOSURE keyword for output products.
corrective action: EXPOSURE keyword not written
 
NoRGSExposurewarning 
 No EXPOSURE keyword in RGS event list. Cannot write exposure value to the product file.
corrective action: Exposure calculation aborted. Execution continues.
 
RGSprodAttributeswarning 
 Could not find requested RGS attributes to copy to the product extension.
corrective action: Execution continues.
 
NoCCDcolumnwarning 
 Event list does not have a CCDNR column. Cannot calculate EXPOSURE keyword for EPIC products.
corrective action: Exposure calculation aborted. Execution continues.
 
NoOutputwarning 
 Input parameters have been set such that no output will be produced and no input files modified.
corrective action: Immediately exit program.
 
ExpNoDsswarning 
 The user has requested that exposure information be updated without the writing of the data subspace (writedss set to false). This means it is likely that all filter information will not be taken into account when updating the exposure information. In general, writedss should be set to true when updateexposure is set to true.
corrective action: Execution continues.
 
ExpBadDsswarning 
 An error occurred while parsing and processing the data subspace information. This means it is likely that all filter information will not be taken into account when updating the exposure information.
corrective action: Execution continues.
 
FrameTimeBiggerThanPeriodwarning 
 Check phase expression.
corrective action: Execution continues.
 
NoFrameTimeKeywordFoundwarning 
 Check event list.
corrective action: Execution continues.
 
NoExpEmptywarning 
 The exposure calculation cannot be performed for an empty event list, as it is a weighting of the number of photons in the various CCDs.
corrective action: Exposure calculation aborted. Execution continues.
