CIAO 4.0 Beta 2 Release Notes


[New] (14 Sep 2007) CALDB 3.4.1 has been released.

The CIAO 4.0 Beta 2 release includes a new, more powerful version of ChIPS, the CIAO plotting package. It can be used during data analysis - e.g. to plot a lightcurve - and to create publication-quality figures. Details and documentation on the new system is available from the ChIPS website.

Several bug fixes to the CIAO tools are also included.

Sherpa is not included in CIAO 4.0 Beta 2. It will be released in Beta 3 (Fall 2007).
