CIAO 4.0 Beta 1 Release Notes


The most notable change in CIAO 4.0 Beta 1 is that the ACIS dead area correction is turned on by default; refer to the How CIAO 4.0 Beta 1 and CALDB 3.4.0 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 solution which, among other uses, 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.

CIAO 4.0 Beta 1 is the first release of CIAO to be 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.

CALDB 3.4.0 is required for the proper operation of CIAO 4.0 Beta 1. CALDB 3.4.0 contains a number of updates, including ACIS time-dependent gain files, updated ACIS blank-sky background files, and HRC-I gain maps.

ChIPS and Sherpa are not included in CIAO 4.0 Beta 1. They will be released in CIAO 4.0 Beta 2 (Summer 2007) and Beta 3 (Fall 2007), respectively.



How CIAO 4.0 Beta 1 and CALDB 3.4.0 Affect Your Analysis

Parameter Files

The CIAO 4.0 Beta 1 software establishes a separate local parameter file directory, ~/cxcds_param_beta. This allows users to run both CIAO 3.4 and CIAO 4.0 Beta 1 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.
