Revision no. Date Author Comments
1.73.2 14 Aug 2007 RDS Full support for spatial masks.
1.71 06 Sep 2006 RDS Find the cross-region ARF.
1.70 24 Mar 2006 RDS Calculates PSF correction for Timing/Burst.
1.69.1 16 Jan 2006 RDS Defaults negative backscale to zero.
1.69 21 Dec 2005 RDS Full treatment of event flags.
1.66.3 1 Aug 2005 RDS Addition of ignoreoutoffov parameter.
1.65.16 13 Aug 2004 RDS The default attitude selection useodfatt has been changed to use the values in the spectrum header rather than the ODF. The default photon energy for PSF use has been changed from 5 to 2 keV. Rudimetary support has been added for spatial masks.
1.65.9 24 Feb 2004 RDS More details of Timing/Burst mode processing.
1.65.4 21 Jan 2004 RDS Warning added for PN timing mode spectra with wrong pattern range.
1.65 18 Dec 2003 RDS ARF reduction due to area outside the FOV , outside an observing window, on an excluded CCD or a bad column is now supported.
1.54 29 Oct 2002 RDS Added support for Timing and Burst modes
1.53 19 Sep 2002 RDS Explains the use of PATTERNs within arfgen and describes the latest warnings for incorrect patterns. Adds an extra TEL option to the sourcecoords parameter.
1.48 25 Feb 2002 RDS Uses the observing mode to generate the Q.E. using pattern fractions. The Q.E. is applied for each detector map position.
1.47 10 Dec 2001 RDS Removed the parameters pattermin, patternmax,withpatterns and added modelootcorr. Added description for out-of-time event corrections. Better explanation for extended sources.
1.45 15 Aug 2001 RDS The simpler PSF treatment is now applied to annuli. Includes information on some warnings produced by the CAL package.
1.44 03 May 2001 RDS extra parameters: withbadpixcorr, badpixlocation, setbackscale, keeparfset, useodfatt. Code now coorects for chip gaps and bad pixels. The attitude may be obtained from the RA/DEC/PA values in the spectrum header (useodfatt=no). A simpler PSF definition is used for circular source boxes. Source position now uses the centre of the source region by default. Calculates the BACKSCAL (area of source region) for the spectrum and writes it into spectral file (setbackscale, keeparfset).
1.41.9 03 Nov 2000 HS Further improvements to the detector map and examples sections. Removed parameters photondistset, datalabel and modelpileup.
1.41.7 31 Oct 2000 HS Updated sections discussing future work.
1.41.6 30 Oct 2000 HS Added description for psfenergy
1.41.5 20 Oct 2000 HS Region bounds check warnings modified. Global attributes read from spectrum dataset updated. Text concerning region bounds check modified slightly.
1.41.4 19 Oct 2000 HS Added new parameter psfenergy. Moved Examples section to top of documentation. Renumbered versions in Change History section.
1.41.3 15 Oct 2000 HS Updated minimum constraints to patternmin, patternmax and eegridfactor. Re-worded ranges for other parameters.
1.41.1 14 Oct 2000 HS Updated attributes in attcalc internal call.
1.41 09 Oct 2000 HS Extended default values for detxoffset and detyoffset to 400
1.40 06 Oct 2000 HS Added pattern support (for QE modelling), and warnings are raised if selected region extends beyond bounds of detector map.
1.36 26 Sep 2000 HS Added new parameter: filterdss.
1.35 31 Aug 2000 HS Discussed detector map usage in more detail. Mentioned attcalc call optimization.
1.34 07 Aug 2000 HS Now filters detector map using region(s) described by the DSS attributes/blocks in the input spectrum as opposed to the SLCTEXPR attribute. The filtered product is used in the main ARF generation loop in addition to the encircled energy correction stage.
1.33 01 Aug 2000 HS Added new parameter withsourcepos and replaced parameters detxmin,detxmax,detymin,detymax with detxoffset and detyoffset. Dummy detector map option renamed to 'flat'. Extended examples section to describe task usage
1.32 28 July 2000 HS Removed constraint that detmaps need to be of type real-64.
1.28 13 July 2000 HS PN support discussed.
1.27.4 30 June 2000 HS Added description of oal usage.
1.27.2 15 June 2000 HS Use separate latex macros for individual elements in a list. Removed latex \task macro around another appearance of the word 'detmapgen'.
1.27.1 15 June 2000 HS Removed latex \task macros around the words 'XSPEC' and 'detmapgen'.
1.27 29 May 2000 HS Changed default values of xbins and ybins to shorten default execution time.
1.26 25 May 2000 HS Removed RGA grating correction feature - this is taken into account by CAL.
1.25 10 May 2000 HS Updated description based on comments from J Ballet and J Osborne. Added a new type of internal detector map to support point sources. The source position can now be specified in terms or RA/DEC X/Y or DETX/DETY coordinates. Removed parameter spliteventset.
1.21 24 Mar 2000 HS Updated description to reflect current functionality, specifically the detector map implementation and encircled energy correction.
1.19 - HS Added description for detector map feature. Updated parameter section.
1.18 - HS Added an Invocation section, describing how to run the task from the GUI and from the command line.
1.16 - HS Removed functionality stated in version 0.5, that involved having the main pile-up correction in rmfgen, and that rmfgen would produce an RMF+ARF dataset. This is now described in the Future Developments section. Reverted to the original proposal in which rmfgen would generate an RMF only, and arfgen the ARF. Pile-up correction will not be developed further in the short term. Added a description for the new spatial filtering mechanism. Added description for point/extended source support. Renamed parameters according to new SAS convention.
1.8 - HS Moved main pile-up correction procedure to rmfgen. Task can still correct for flux loss, but such a feature should only be used in special circumstances.
1.7 - HS Ported code over to C++. Added correction for flux loss due to encircled energy (MOS). Added correction for flux loss due to pile-up (MOS only)
