Hello, Chandra Users,
See the CIAO "What's New" web page
http://cxc.cfa.harvard.edu/ciao/news.html
for the following announcements:
I. CIAO Scripts Package updates:
The CIAO team has released an update to the CIAO science scripts
tarfile. This new file may be downloaded via ciao-install
(http://cxc.harvard.edu/ciao/download/) - which will also install the
new CALDB changes - or from the CIAO Scripts Page
(http://cxc.harvard.edu/ciao/download/scripts/).
The changes in this release are:
o) The merge_all script is now deprecated (although still available);
please use one or more of the merge_obs, reproject_obs, or
flux_obs scripts which are new in this release.

Threads:

http://cxc.harvard.edu/ciao/threads/reproject_image/
o) fluximage
http://cxc.harvard.edu/ciao/ahelp/fluximage.html
The fluximage script has seen a large number of improvements,
including a change to the parameter interface, support
for using spectral weight files, and changes to the file
naming scheme to match merge_obs.

o) chandra_repro
http://cxc.harvard.edu/ciao/ahelp/chandra_repro.html
* the script can now process multiple observations in one go
* files are now copied, rather than linked (this reverses a
change made in the April 2012 release)
o) a large number of color look-up tables has been added for
use in ChIPS and ds9.

II. CalDB 4.5.3 released:
As promised in my email of 04 October 2012, CalDB 4.5.3, with the
*re-correctons* of the ACIS Group E blank-sky background data datasets,
is now ready for download and installation. CalDB 4.5.3 corrects a
secondary file block structure error that appeared in the CalDB 4.5.2
release of 27 Sep 2012. That error caused a failure in
acis_bkgnrd_lookup, and has now been corrected.
The upgrade may be installed automatically using the "ciao-install"
script, newly updated for the CalDB 4.5.3 tar files, which is available at:
http://cxc.cfa.harvard.edu/ciao/download/
The release notes for CalDB 4.5.3 are included here:
http://cxc.cfa.harvard.edu/caldb/downloads/Release_notes/CALDB_v4.5.3.html
and user information on "How CalDB 4.5.3 Affects Your Analysis" is at:
If you would prefer to download and install CalDB 4.5.3 manually, you
may access the CalDB Download Web page at:
http://cxc.cfa.harvard.edu/caldb/downloads/index.html
for explicit instructions.
----------------------------------------
As always please send questions and requests for enhancements to the CXC
HELPDESK (http://cxc.harvard.edu/helpdesk/).
CIAO/CALDB is a collaborative effort between the SAO/CXC Science Data
Systems, the SAO/CXC Data Systems, and MIT/CXC personnel.
Cheers,
Dale Graessle
Chandra CalDB Manager
