CIAO 3.3 Release Notes


CIAO 3.3 has been patched to CIAO 3.3.0.1. The CIAO 3.3.0.1 patch contains a PIMMS effective area file upgrade required for Cycle 8 proposal planning.

CALDB version 3.2.1 was released on 15 December 2005. Information on the changes in this release is in the How CALDB 3.2.1 Affects Your Analysis section of these release notes.

The CIAO 3.3 software release includes three new tools useful for reprojecting files with different coordinate WCS (reproject_aspect, reproject_image, and reproject_image_grid). It also includes a new tool for extracting ACIS spectra - specextract - which automatically uses the most appropriate response tool to create the RMF and replaces most of the functionality of the psextract and acisspec scripts. CIAO 3.3 includes several improvements and bug fixes, most notably significant changes to the region library which fix a number of problems in the calculation of region areas. Additionally, error calculation changes in dmextract and dmgroup improve the compatibility of the output files with XSpec.



How CALDB 3.2.1 Affects Your Analysis

CALDB 3.2.1 was released on 15 December 2005. This release contains a number of calibration improvements.

Note that there is no compatibility problem if you upgrade to CALDB 3.2.1, but continue to use CIAO 3.2.2.

How CIAO 3.3 and CALDB 3.2.0 Affect Your Analysis

Some tool changes and calibration files released in CIAO 3.3 and CALDB 3.2.0 affect analyses in progress, i.e. certain processing steps should be run again for greater accuracy. This section of the release notes describes those changes, as well as the affected tasks.

Note that there is no compatibility problem if you upgrade to CALDB 3.2.0, but continue to use CIAO 3.2.2.

Bug Fixes


ds9

CIAO 3.3 contains ds9 v4.0b7, which runs on OS X 10.3 or higher.

If you are using OS X 10.2, you will need to customize your installation to use ds9 v3.0.3 (also packaged with the CIAO 3.3 software).

unix% cd $ASCDS_INSTALL/ots/saord/ds9_dir
unix% mv ds9 ds9.4.0
unix% mv ds9.3.0.3 ds9

Sherpa

There was no development done on Sherpa for CIAO 3.3, other than this one bug fix.

Bug Fix


ISIS

ISIS has been upgraded to version 1.3.0.
