Analysis Notes

Matching CIAO and CALDB Versions

CIAO 4.0 requires CALDB 3.4.0 or higher to operate properly.

Are your versions mismatched? Time to update CIAO and CALDB!

Source Detection and Cosmic-Ray Afterglows

CIAO users who are trying to detect sources of about 10 counts or less should be aware of potential confusion with cosmic-ray afterglows that have not been removed from the data.

The Cosmic-Ray Afterglows why topic explains the limitations of the current tools and describes analysis tips to help eliminate more of the afterglows.

The CXC announces the return of the Chandra/CIAO workshops. This is the sixth in a series of workshops started in 2001 aimed at helping users to work with the Chandra Interactive Analysis of Observations (CIAO) software.

The 6th Chandra/CIAO Workshop will be held 20-22 October 2008 at the Chandra X-ray Center in Cambridge, MA (USA). Registration is now open!

Several of the CIAO contributed scripts were updated to replace the Unix "head" and "tail" commands with the CIAO tools "dmkeypar" and "pget". A user reported script failure on Mac OS X 10.4 Intel due to incompatible syntax.

16 Apr 2008

CIAO has been patched to CIAO 4.0.2.

The CIAO 4.0.2 patch enables CIAO to run on Mac OS X 10.5 (Leopard) Intel. The patch is optional for 10.4 (Tiger) Intel machines.

The patch should not be applied to Linux, Solaris, or Mac PowerPC installations of CIAO.

Download the 4.0.2 patch.

Additionally, there is an updated standalone version of ObsVis for Mac OS X Intel; see the ObsVis website for details and the download.

Bugs fixed in CIAO 4.0

The following is a list of bugs that were fixed in the CIAO 4.0 software release.

  1. Tool fails if obsfile needed and not supplied (01 Dec 2006)

    The obsfile is a necessary input when doing the CALDB lookup. If acis_build_badpix requires this parameter and it is empty, the tool segmentation faults.
