The Chandra X-ray Center (CXC) is pleased to announce that version 3.4
of CIAO ("Chandra Interactive Analysis of Observations") and version
3.3.0 of CALDB are now available for download from:
http://cxc.harvard.edu/ciao/download/
They will also be available from the European mirror site at:
http://ledas-cxc.star.le.ac.uk/ciao/download/
-----------------------------------
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. Finally,
this release includes the PIMMS effective area file upgrade required
for Cycle 9 proposal planning.
For complete information on this release, please see the full Release
Notes (http://cxc.harvard.edu/ciao/releasenotes/) which also include the

Database CALDB 3.3.0 which contains a new ACIS calibration suite
(N0006), ACIS QE and QEU files, time-dependent HRC-I gain maps and an
HRC-S RMF suitable for calibrating hardness ratios or creating
quantile color-color diagrams.
