CIAO 4.0 Release Notes


[New] (8 Sep 2008) CALDB has been patched to version 3.5.0. The How CALDB 3.5.0 Affects Your Analysis section has information on the release.

[New] (16 Apr 2008) CIAO has been patched to CIAO 4.0.2 on Mac OS X Intel only. This patch enables CIAO to run on Mac OS X 10.5 (Leopard) Intel; it is optional for 10.4 (Tiger) Intel. The patch should not be applied to Linux, Solaris, or Mac PowerPC installations of CIAO.

CIAO 4.0.2 Release Notes


CIAO 4.0 is a full installation of the CIAO software. It contains all the enhancements and bug fixes since CIAO 3.4, including those which were made available in the 4.0 Beta releases.

The most notable change to the CIAO tools in version 4.0 is that the ACIS dead area correction is turned on by default; refer to the How CIAO 4.0 and CALDB 3.4.2 Affect Your Analysis section for details. There is a new version of tgextract - named tgextract2 - which provides similar functionality, but allows large and asymmetric regions for better determination of background counts. Significant work has been done on the tool wavdetect, which has two new parameters. The sso_freeze tool has been enhanced so that it can create object-centered aspect solutions which allows an object-centered exposure map to be generated. A number of bug fixes to the Data Model library and several CIAO tools are also included.

The Data Model library now supports an ASCII kernel. This kernel allows users to generate ASCII format files for use within Data Model enabled tools (e.g. dmlist, dmcopy), and apply the suite of Data Model capabilities to those files via its extended filename syntax. The ASCII kernel is considered beta for this release.

The CIAO 4.0 release includes a new, more powerful version of ChIPS, the CIAO plotting package. It can be used during data analysis - e.g. to plot a lightcurve - and to create publication-quality figures. Details and documentation on the new system is available from the ChIPS website.

This release also features an experimental (beta) version of the new Sherpa, the CIAO modeling and fitting package. Details and documentation on the new system are available from the Sherpa website.

CIAO 4.0 is fully GPL compliant. OTS (off-the-shelf) software have been updated to current versions. A set of "smoke test" scripts are included to aid users in verifying installation of the release.

Parameter Files

The CIAO 4.0 software establishes a separate local parameter file directory, ~/cxcds_param4. This allows users to run both CIAO 3.4 and CIAO 4.0 without having to worry about parameter file conflicts.

A summary of parameter files changes is provided in this section. Refer to the Tools section of these release notes for complete details.
