Item 2. CIAO2.3 coming in November
==================================


A new version of CIAO is planned for release this November.

CIAO 2.3 will include everything needed to apply and use the new ACIS
`charge transfer inefficiency' (CTI) correction to obtain improved
energy resolution.

In particular:
- New CTI correction algorithm in acis_process_events 
- Automatic lookup of CTI corrected calibration files (gains, OSIPs, and
FEF files) 
- Support for latest CTI corrected FEF Files. mkrmf will calculates PI
matrices from PHA FEFs on-the-fly; this means that CTI-corrected PI FEFs
are unnecessary. 

Also being included in the release are: 
- A pixlib upgrade which contains a correction for the LETG Rowland
diameter problem. 
- An upgrade to the history mechanism. 
- A Sherpa upgrade to allow the pileup model to be used when channels are 
being ignored.


- Various small bug fixes and enhancements.

Item 3. CHANDRA Calibration Workshop/CIAO Expert Sessions 
=========================================================


Don't miss the opportunity to learn everything you always wanted to
know about the calibration of CHANDRA as well as how to solve your
thorniest issues with analysing your CHANDRA data at the upcoming
CHANDRA Calibration Workshop/CIAO Expert Sessions on November 5-8 in
historic Boston. Tons more information as well as registration and
abstract submission forms can be found at http://cxc.harvard.edu/ccw_02/
