If not, see . --------------------------------------------------------------------- Version 3.12.2 - 2012-03-28 (IT) ------------------------------ + Coordinates in match table: X_RA and X_DEC are set to the coordinates in the input X-ray source list (instead of intermediate results; SPR-6635). + Optical input source list: RA, DEC, and RADEC_ERR columns can be given in single or in double precision (user request in March 2012; SPR-6701). + Updated documentation. Version 3.12.1 - 2008-05-09 GL ----------------------------------- Correct an error with using the parameter rawxsyserr, introduced in v 3.9.2. Close SOC-SPR 6436 (SSC-SPR 3701). Version 3.12 - 2007-05-25 GL ----------------------------------- Fixed documentation. Version 3.11 - 2006-05-23 GL ----------------------------------- Copy of 3.9.3 for SAS 7 Version 3.9.3 - 2006-02-07 GL ----------------------------------- Updated documentation Version 3.9.2 - 2005-06-21 GL ----------------------------------- Changed column names containing "-" in match table: X-INDEX -> X_INDEX X-RA -> X_RA X-DEC -> X_DEC O-INDEX -> O_INDEX O-RA -> O_RA O-DEC -> O_DEC Look for RA_PNT/DEC_PNT in both PRIMARY array and source list extension. Write axis information of the likelihood image as physical coordinate system. (see SSC-SPR-3305) Improve efficiency by a large factor a) by reusing results of rotational coordinate transformations. b) by reducing the input list to 1 row per source already on reading the source list. Write likelihood bias expected due to optical background source density into keyword LIK_NULL of the corrected source list. (see SSC-SPR-3493) Update test harness Version 3.10 - 2004-03-19 GL ----------------------------- Fixed problem that caused segmentation fault, when no error column was present in optical catalogue. Version 3.9.1 - 2002-03-02 GL ----------------------------- Change coordinates in matchtable to double precision. Version 3.9 - 2002-12-08 GL ----------------------------- Make use of param v2 features in .par file Version 3.8 - 2002-10-29 GL ----------------------------- Update DEPEND Created lyt file Changed info file Closed SPR: + SSC-SPR-2926 misleading duplicate error code. Version 3.7 - 2002-05-24 GL ----------------------------- Based on v3.4.2 + Converted .par file to XML Version 3.4.2 (2002-05-15) HB ----------------------------- New task parameters added: rawxsyserr,r,h,1.5,,,"systematic error of input X-ray positions" minxsyserr,r,h,0.2,,,"irreducible systematic error of X-ray positions" maxsig,r,h,5.0,,,"sigma cutoff for X-ray/optical matches" usemaxsig,b,h,yes,,,"use sigma cutoff limit" maxposnerr internally multiplied by sqrt(0.5) to achieve consitency with RADEC_ERR values Closed SPR: + SSC-SPR-2863 inproperly fixed SPR 2830 corrected Version 3.6 (2002-04-20) HB --------------------------- Closed SPR: + SSC-SPR-2830 Number of matches does not account for multiple rows Version 3.5 (2000-01-28) HB --------------------------- -Error in parameter file corrected Version 3.4 (2001-10-17) HB --------------------------- -error in the test harness corrected Version 3.3 (2001-10-13) HB --------------------------- -units of RA, DEC, and error columns now read from source table -position error column no longer required -optional output of table containing matched sources with distances and likelihood contributions for each matched pair -RA, DEC offsets and rotation angle can optionally be specified as input parameters instead of being determined by the programme -column names for R and B magnitues now specified by input parameter Version 3.2 (2001-08-13) HB --------------------------- Closed SPRs: + SSC-SPR-2486 Fails to compile with NAG F95 4.1 + SSC-SPR-2357 Allow correlating X-ray sources with one another + SSC-SPR-2316 SCR 56task puts too many restrictions on input file Version 3.1.1 (2001-06-01) HB ----------------------------- Closed SPR: + SSC-SPR-2414 broken link in HTML doc Version 3.1 (D.M., September 22., 2000) ---------------------- + Possibility to reduce positional error by only considering strong sources with low positional error: Parameter maxposnerr Version 3.0 (JV, Juli 21, 2000) ---------------------- + Possibility to search for rotational errors added (but is still slow) + Parameters added/changed Version 2.0.1 (JV, June 16, 2000) ---------------------- + missing info file added + changed the internal error representation as there was a discrepancy between documentation and code. + as a consequence the test harness had to be changed as well Version 2.0 (JV, June 2000) ---------------------- - Changed the names of keywords added by eposcorr to the source list data set. - Added some additional keywords. - Parameters added in order to select R and B magnitudes from the input optical set. Version 1.1 ---------------------- - The task has been updated to work properly with the latest summary srclists. See SSC-SPR-1272, 1273, 1274 - Added a keyword describing the approximate error in the position correction applied. Version 1.0 ---------------------------- Remarks about this version. This version is similar to v 0.1, but I have changed the test files and removed the *.cc files. See SSC-SPR-1253, SSC-SPR-1248, SSC-SPR-1129, SSC-SPR-1117. Open SPRs: SSC-SPR-1253 - 1234 Version ---------------------- Remarks about this version. Open SPRs: - 1234 Version 0.1 ---------------------------- - Directory structure created by pkgmaker.
