CIAO 3.4 Release Notes


[New] (02 Feb 2007) CALDB has been patched to version 3.3.0.1.

[New] (29 Jan 2007) CIAO patches for Mac OS X 10.4 on PowerPC and Intel have been released. Refer to the CIAO 3.4.1 and 3.4.1.1 Release Notes for information.

The CIAO 3.4 and CALDB 3.3.0 releases primarily consist of changes related to the CTI corrections. The CTI-adjustment algorithm included in acis_process_events now accommodates the newly calibrated serial CTI on the back-illuminated CCDs. This is in addition to the continued support for parallel CTI. This CIAO release also contains two new tools for working with HRC data (hrc_build_badpix, hrc_dtfstats) and the ability to update WCS in non-Chandra images (reproject_aspect, wcs_match, wcs_update). Significant work has been done on the tool psf_project_ray, which has four new parameters. Plus bug fixes to the Data Model library and several CIAO tools.

How CIAO 3.4 and CALDB 3.3.0 Affect Your Analysis

Some tool changes and calibration files released in CIAO 3.4 and CALDB 3.3.0 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, arranged by instrument and grating configuration.

Reprocessing your data ensures that the newest calibration available is applied consistently through the analysis. Follow the Create a New Level=2 Event File thread if you know you want to reprocess and are not concerned about the details of the calibration changes.

CALDB 3.3.0 is required for the proper operation of CIAO 3.4. Likewise, do not update to CALDB 3.3.0, unless you are using CIAO 3.4.

ds9

CIAO 3.4 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 3.4 software).

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

Sherpa

There was no development done on Sherpa for CIAO 3.4.
