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.

NonStandardSpectrum		error
	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.
NotXmmSpectrum		warning
	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.
NoAttrib		warning
	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.
MinParamRange		warning
	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.
MaxDataRange		warning
	Data values found outside of allowed range for column; will be ignored. corrective action: Values greater than the maximum allowed value will not be used for product extraction
NoInputEvents		warning
	The input event table contains no events (zero rows). corrective action: None - empty product files may be produced
NoFilteredEvents		warning
	No events have been selected during the filtering process. corrective action: None - empty product files may be produced
BadHistoLimits		warning

BadHistoLimits		error
	The column used for histogram extraction has its upper limit less than its lower limit.
HistoColumnName		warning
	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.
XlimitEpsilon		warning
	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.
YlimitEpsilon		warning
	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. corrective action: Y axis upper limit adjusted by an epsilon amount.
BadImgLimits		warning
	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. corrective action: No image is created.
NoWCS		warning
	No WCS information is available for an image column. corrective action: Pixel based WCS information is written to the output image.
BinVsFrameTime		warning
	Time bin size is less than the mean frame readout time. corrective action: No action taken.
RateEnergy		warning
	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.
BadRateLimits		warning
	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.
BadRateLimits		error
	The column used for light curve extraction has its upper limit less than its lower limit
BadSpecLimits		warning
	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.
BadSpecLimits		error
	The column used for spectral extraction has its upper limit less than its lower limit
NotXMM		warning
	Can only update exposure information on XMM data. No updating of exposure information is performed. corrective action: Exposure information is not updated.
RgsTimeFilter		warning
	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.
NoTargetOntime		warning
	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.
NoTargetLivetime		warning
	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.
ExpMultiCcdFilters		warning
	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
ExpBadCcdType		warning
	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
ExpBadCcdComp		warning
	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
ExpBadTimeType		warning
	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
ExpBadTimeComp		warning
	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
ExpBadGlobalComp		warning
	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
NotXmmProduct		warning
	Not XMM data. Cannot calculate EXPOSURE keyword for output products. corrective action: Exposure calculation aborted. Execution continues.
NoProductExp		warning
	No live time information available. Cannot write EXPOSURE keyword for output products. corrective action: EXPOSURE keyword not written
NoRGSExposure		warning
	No EXPOSURE keyword in RGS event list. Cannot write exposure value to the product file. corrective action: Exposure calculation aborted. Execution continues.
RGSprodAttributes		warning
	Could not find requested RGS attributes to copy to the product extension. corrective action: Execution continues.
NoCCDcolumn		warning
	Event list does not have a CCDNR column. Cannot calculate EXPOSURE keyword for EPIC products. corrective action: Exposure calculation aborted. Execution continues.
NoOutput		warning
	Input parameters have been set such that no output will be produced and no input files modified. corrective action: Immediately exit program.
ExpNoDss		warning
	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.
ExpBadDss		warning
	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.
FrameTimeBiggerThanPeriod		warning
	Check phase expression. corrective action: Execution continues.
NoFrameTimeKeywordFound		warning
	Check event list. corrective action: Execution continues.
NoExpEmpty		warning
	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.
