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.

illegalIPPVvalueerror 
 Parameter IPPV has illegal value, check ODF summary file
 
NoGoodObtValueserror 
 Time computation failed because no good frames could be identified
 
InconsistentTimeInfoerror 
 Time computation is inconsistent, there may be time back-jumps in the data. Submit a report with SAS_VERBOSITY=5.
 
toomanyerror 
 Number of frames larger than allowed limit
 
wrongModeerror 
 Illegal or missing type of data mode or not scientific data mode
 
changedModewarning 
 data mode has been changed: eFF $\rightarrow$ FF or FF $\rightarrow$ eFF
corrective action: continue, ODF seems to be inconsistent
 
CCDlowGainwarning 
 HK values of this CCD indicate that the mode is not HIGH gain
corrective action: continue, energy scale will be incorrect
 
singleBoresightBurstwarning 
 Unusual RAWY event range, dataset may be in SingleBoresight BURST format
corrective action: continue, window and associated flags may be wrong
 
doubleWindowTimingwarning 
 Unusual RAWX event range, dataset may be in double-window TIMING format
corrective action: continue, window and associated flags may be wrong
 
BPTcodewarning 
 BadPixelTable codes in PAH.FITS and ADUCONV.CCF differ
corrective action: continue, probably the EPN_ADUCONV_####.CCF or the whole CIF is incorrect (too old), amplitudes in columns with offset shifts may be wrong
 
missingIPPVwarning 
 Parameter IPPV not found, will set it to default value
corrective action: continue with default value, check ODF summary file
 
misFramewarning 
 Event frame not found in AUX file
corrective action: continue, AUX file may have been created incorrectly
 
eventsNoAUXwarning 
 events file non-empty but AUX file empty
corrective action: continue, AUX file may have been created incorrectly
 
noNGAUXwarning 
 No good AUX1 intervals left for analysis
corrective action: continue
 
noAUX1forCCDwarning 
 No AUX1 entries for this CCD
corrective action: continue
 
noAUX2forCCDwarning 
 No AUX2 entries for this CCD
corrective action: continue
 
PHAoffsetwarning 
 Unusual amplitude range of ODF event list
corrective action: continue, contact task developer
 
corruptedAUX1warning 
 PNAUX1 extension contains impossible values, not nominal ODF
corrective action: continue, may fail for this CCD or other CCDs later
 
noPNAUX1warning 
 PNAUX1 extension missing in AUX file, not nominal ODF
corrective action: continue, skip PNAUX1 related code, time and exposure entries incorrect
 
noPNAUX2warning 
 PNAUX2 extension missing in AUX file, not nominal ODF
corrective action: continue, skip PNAUX2 related code, exposure entries incorrect
 
noPNPMH1warning 
 PNPMH1 extension missing in housekeeping file, not nominal ODF
corrective action: continue, skip PNPMH1 related code
 
noPNPAH1warning 
 PNPAH1 extension missing in housekeeping file, not nominal ODF
corrective action: continue, skip PNPAH1 related code
 
misHKcolumnwarning 
 column expected in HK file but is absent, not nominal ODF
corrective action: continue, skip analysis for this column
 
emptyHKrangewarning 
 no HK values within limits, use all entries in exposure for analysis
corrective action: continue
 
notHKconstantwarning 
 HK value is expected to be constant (or limited to small interval) within the exposure but is not
corrective action: continue
 
HKoffsetmapwarning 
 No offset map calculation interval could be determined for this observation
corrective action: continue
 
OffsetMapwarning 
 HK values indicate that the filter was not the same during intervals of offset map calculation and science exposure or that the offset map calculation interval was not immediately before this exposure
corrective action: continue
 
illegalODFwarning 
 The ODF seems to be inconsistent. See subsection [*]
corrective action: continue, some underlying SAS packages may fail as a consequence
 
FILTERwrongwarning 
 The filter wheel position sensor values do not properly reflect the actual FILTER position, this is overwritten using a black-list, and the FILTER keyword in the primary extension is then correct.
corrective action: continue
 
wrongFC0warning 
 No mode dependent livetime factor
corrective action: set mode dependent livetime factor FC0 = 1
 
wrongFTCoarsewarning 
 Illegal FTCOARSE time value in AUX file
corrective action: give a warning, continue execution
 
FreqShiftLargewarning 
 The oscillator frequency shift derived from HK parameters exceeds the limits given by SAS_JUMP_TOLERANCE or EPN_TIMEJUMPTOL_####.CCF. False time jumps may be introduced by the OAL.
corrective action: continue execution, user may consider re-run according to recommendation given along with the warning
 
srcposwarning 
 BURST mode expects source position in the range 181 to 200
corrective action: give a warning, continue execution
 
wrongCoordwarning 
 invalid event coordinates
corrective action: write an OUT_OF_CCD_WINDOW flag and continue execution
 
wrongReadoutOrderwarning 
 events are in wrong readout order
corrective action: write an IN_BAD_FRAME and IN_SPOILED_FRAME flag, continue execution
 
wrongTimeOrderwarning 
 ODF file not sorted in time
corrective action: write an IN_BAD_FRAME and IN_SPOILED_FRAME flag, continue execution
 
wrongMIPcoordwarning 
 MIP detected with illegal coordinates
corrective action: continue
 
MIPrejectionwarning 
 MIP CORREC.1 was commanded (row-wise) this mode is not fully calibrated
corrective action: continue, background rejection and CTI correction may be incomplete
 
tooLongExposurewarning 
 TELAPSE = TSTOP-TSTART of this exposure is longer than the whole scheduled observation as specified by DURATION = DATE_END-DATE_OBS
corrective action: expoure may be longer than scheduled or event times wrong
 
SubscriptOutOfRangewarning 
  Size is estimated from TSTOP-TSTART divided by the frame time plus margin; in this exposure this appears to be insufficient and therefore time inconsistencies must have occured.
corrective action: EXPOSURE extension becomes larger than allocated arrays
 
date2000warning 
 unusual values of DATE-OBS and/or DATE-END
corrective action: give a warning, continue execution
