Script Update History

Package Version Name Changes
10 Nov 2009 SherpaCL

The PRINT command now takes a GUI option to take advantage of the ChIPS printer dialog window. The output from the CONVERT command has been improved for a number of situations. The ChIPS C and D commands now rok correctly, but no longer support ranges other than "ALL". See 'AHELP CHANGES' from within SherpaCL for more information.

check_ciao_caldb

Updated to avoid a spurious warning message when CALDB version 4.1.4 (or later) is installed.

03 Nov 2009 SherpaCL

A new, interactive interface that allows users to use CIAO 3.4 syntax for Sherpa and ChIPS commands in CIAO 4. The language that can be used is currently limited. Refer to "ahelp sherpacl" and the SherpaCL page on the Sherpa website for more information and usage examples.

lc_clean()
lc_sigma_clip()

Both have been updated to better handle data with "extreme" lightcurves: either by erroring out or being able to create GTI files which contain a large number of time intervals.

The screen output (when verbose is set) has been modified to provide more information on the length of each interval.

deflare New script: allows user to choose between the lc_clean() or lc_sigma_clip() routine from the lightcurves.py module to remove flares from lightcurves.
04 Aug 2009 ciao_contrib The new file ciao_utils.sl was omitted from the 03 August update.
03 Aug 2009 sherpa_contrib The sherpa_utils (S-Lang or Python help) module has been updated to include save_instmap_weights (S-Lang or Python help); its use is described in the Calculating Spectral Weights for mkinstmap (S-Lang or Python) thread.
ciao_contrib A new module - ciao_utils (S-Lang or Python help) - has been added; it contains two routines for data analysis: simple_stats (S-Lang or Python help) and simple_hist (S-Lang or Python help).
check_ciao_caldb The script has been updated to check the existence of the CALDB in a more intelligent way. Functionality is unchanged.
01 June 2009 fullgarf If bad pixel file is not supplied, use the one from the CALDB. Previously, the script would set the bad pixel file to "NONE" in this case.
merge_all
  • check that intdir directory exists and is writeable
  • run punlearn before running mkinstmap
17 Apr 2009 crates_contrib
sherpa_contrib
ciao_contrib
New modules have been added: crates_contrib (S-Lang or Python help), sherpa_contrib (S-Lang or Python help), and ciao_contrib (S-Lang or Python help) (loads both crates_contrib and sherpa_contrib). Refer to the help files for details.
check_ciao_caldb The check_ciao_caldb script tests the installation of the CIAO Calibration Database (CALDB).
02 Mar 2009 chart_spectrum The chart_spectrum.sl/chart_spectrum.py script has been updated for CIAO 4.1; it creates a spectrum file for input to the Chandra Ray Tracer (ChaRT). The Preparing to Run ChaRT thread (S-Lang or Python) shows how to use the script.
05 Jan 2009 acis_bkgrnd_lookup The script now includes the blname parameter which determines whether the block identifier of the output file is included in the output, and what form this identifier should take (e.g. the block name, the DataModel number, or the CFITSIO number).
15 Dec 2008 multiple scripts The scripts package has been updated for the CIAO 4.1 release. The Analysis Scripts section of the release notes has a list of all the changes made.
