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.

noSrcArea		error
	The task calculated that no events from the source data set passed the selection expression.
badInstrument		error
	Instrument not supported.
tsNoData		error
	There are no rows in the time series RATE table.
tsTooManyEbands		error
	The time series contains data in more than the 1 allowed energy band.
tsBadTimeUnits		error
	The time series has inconsistent time units.
tsNoTimes		error
	The timeseries has neither a TIME column nor a TIMEDEL keyword.
tsDifferentInstrumeKwds		error
	When a background series is supplied: source and background timeseries INSTRUME keywords don't match.
tsDifferentTimeunitKwds		error
	When a background series is supplied: source and background timeseries TIMEUNIT keywords don't match.
tsDifferentMJDrefKwds		error
	When a background series is supplied: source and background timeseries MJDREF keywords don't match.
noTimeDel		error
	No TIMEDEL information (either column or keyword) was found in the file.
bkgTimeBinsLeZero		error
	When a background series is supplied: an error during the rebinning.
srcTimeBinsLeZero		error
	When a background series is supplied: an error during the rebinning.
bkgErrorsNegative		error
	When a background series is supplied: one or more of the background ERROR values was fond to be negative.
badTimeDel		error
	The value of the TIMEDEL keyword is significantly different from the approximate value calculated from the time series itself.
tsBadUncertaintyType		error
	The POISSERR keyword is set to F, but there is no ERROR column.
tsCountsLeZero		error
	COUNT values < 0 detected.
evlistWrongInstrument		error
	The INSTRUME keyword in the event list doesn't match that of the time series.
noDss		error
	The time series has no data subspace. The task cannot determine which filtering criteria were used without this.
noDssComponents		error
	The data subspace of the time series has 0 components. The task cannot determine which filtering criteria were used in this case.
noCcdsPassDss		error
	The data subspace of the time series will not pass any values of CCDNR.
evlistWrongTimeunit		error
	The TIMEUNIT keyword in the event list doesn't match that of the time series.
evlistWrongMJDref		error
	The MJDREF keyword in the event list doesn't match that of the time series.
noExposuExtensions		error
	Events were selected for a CCD for which there is no EXPOSUnn extension in the event list.
badInstrumeMode		error
	The instrument mode is unrecognized or unsupported by lccorr.
unableGetSrcPosFromDss		error
	Source position extraction from the DSS was requested, but this was not possible.
badSrcPosStyle		error
	Unrecognized value of srcposstyle.
noCcdFiltersInDssComponent		error
	Bad DSS.
noFilterThisCcdInDssComponent		error
	Bad DSS.
badChanType		error
	Unrecognized value of the CHANTYPE keyword. Currently the only value recognized by lccorr is `PI'. The value is set, at the time the time series is made, from the value of the -energycolumn parameter of evselect. Unfortunately the default for this at time of writing is `PHA' so to make time series which lccorr will accept you will need to set the -energycolumn value to `PI' explicitly.
noERangeOverlap		error
	The energy ranges of the time series and the DSS don't overlap.
badRegridStatus		error
	Something went wrong with the rebinning of the PSF samples cube. You should contact the code developer.
badBadPixType		error
	The value of the TYPE column of the BADPIXnn table was not recognized.
badFlagFilter		error
	The bit-mask filter on column FLAG obtained from the data subspace was not well-formed.
noBkgArea		warning
	The task calculated that no events from the background data set passed the selection expression. corrective action: The background time series in the output will be zero-valued.
deprecatedUnit		warning
	The unit of the time column was read as `SECONDS', but the OGIP standard specifies `s'. corrective action: `s' is assumed.
tsHasBackv		warning
	The time series has a background column. corrective action: This column will be discarded.
noOverlap		warning
	When a background series is supplied: the background timeseries does not overlap in time at all with the source timeseries. corrective action: The background columns in the output will be filled with nulls.
onlyPartialOverlap		warning
	When a background series is supplied: the background timeseries does not entirely overlap in time with the source timeseries. corrective action: The non-overlapping rows of the background columns in the output will be filled with nulls.
tsNoPoisserrKwd		warning
	There is neither a POISSERR keyword nor an ERROR column in the time series. corrective action: Poissonian errors assumed.
illegalTwoAxisDssFilter		warning
	The data subspace contains a two-axis filter on a pair of event-list columns outside the set X/Y. RAWX/RAWY, DETX/DETY. corrective action: The task ignores this filter.
illegalDssFilterAxis		warning
	The data subspace contains a filter on column PHA of the event list: but lccorr cannot deal with this. corrective action: The task ignores this filter.
timeSelectionTooComplicated		warning
	The task can handle only 1 type of time filter per CCD. However, a more complicated time-filtering scheme was found in the data subspace. corrective action: The filter is ignored.
allSpatialMapsEmpty		warning
	None of the maps of spatial selections contained non-zero pixels for any CCD. corrective action: None
dubiousDssEnergyRange		warning
	The energy selection recorded in the DSS appears to extend beyond the energy limits given by the E_MIN and E_MAX keywords of the time series. corrective action: The DSS limits will be used. However the resulting exposure values might be inaccurate.
dubiousCalEnergyRange		warning
	The energy limits given by the E_MIN and E_MAX keywords of the time series appear to extend beyond the maximum extent of the energy limits defined in the cal. corrective action: The smaller (ie, cal) limits will have to be used.
badBadPixCoords		warning
	RAWX$<$ 0, RAWX$>$ 1+chipXsize, RAWY$<$ 1 or RAWY+YEXTENT$>$ 1+chipYsize. corrective action: Task ignores this row of the BADPIXnn table.
inconsistentNodeInfo		warning
	The CLOSE_TO_NODE_BOUNDARY event attribute was set, but lccorr can't find any bits of the flag mask with this value. corrective action: No action.
pointlessWindowSelection		warning
	The CLOSE_TO_CCD_WINDOW event attribute was set, but no events get flagged with this value by the MOS software when the window occupies the whole ccd. corrective action: No action.
