Hello, Chandra users,
The latest upgrade to the Chandra CalDB, version 4.2.1 (for use with
CIAO 4.2) has just been released.
For an automated installation of this upgrade, see the CIAO downloads
web page, at http://asc.harvard.edu/ciao/download/ and follow the
instructions there. If you have already installed CIAO 4.2 and CalDB
4.2.0, the script will install the new CalDB version.
Alternatively, see the CalDB downloads web page at
http://asc.harvard.edu/caldb4/downloads/index.html
for *manual* download and installation instructions. If you have already
installed CIAO 4.2 and CalDB 4.2.0, the manual upgrade-only patch in
"TABLE 2" has been provided, for a quicker upgrade installation. (We'll
automate the quick patch files into the ciao-install script for the next
CalDB release. For now, it is manual-only.) Manual full-download
instructions for CalDB 4.2.1 are also included.
RELEASE NOTES:
The 4.2.1 upgrade includes the following:
- ACIS EPOCH 40 T_GAIN files (Nov '09-Jan-'10)
- ACIS BKGRND blank-sky files Group "E" (effective 2005-09-01)
- LETG Grating Efficiencies N0006 (adjustments to orders 2-7)

Cheers,
