Hello, Chandra Users!
READ THIS IF: you are still using *CIAO3.4* and are interested in the
latest calibration update.
Hello, CIAO 3.4 users only!
Good day to the rest of you, who should ignore the following
CalDB upgrade message, which is for CIAO 3.4 installations only!
We have today released CalDB version 3.5.1, which includes the latest
ACIS T_GAIN data for Epoch 35 (August-October 2008). This upgrade
ensures you are able to get the latest calibrations into your
processing and analysis with CIAO 3.4.
[NOTE: We will be maintaining a separate CalDB, compatible with CIAO
3.4, for the near future, as public releases. They will
continue to be versioned as "3.x.x". CalDB 3.x.x will also be
used in Standard Data Processing, and Level 3 processing, until
those software systems are upgraded for the new Chandra CALDB4
installation.]
You may download the new tar ball, with unpacking instructions
and a MANIFEST, from the web page
