Matching CIAO and CALDB VersionsCIAO 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 AfterglowsCIAO 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. 07 May 2008 Information about installing CIAO on unsupported platforms has been added to the Platforms webpage 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. Additionally, there is an updated standalone version of ObsVis for Mac OS X Intel; see the ObsVis website for details and the download. 16 Apr 2008 Mac OS X platforms: FITS table file writing slowness with NFS-mounted disks. FITS table file writing through the CXC Data Model slows by a significant factor on Mac OS X machines - both 10.4 (Tiger) and 10.5 (Leopard) - when the data is accessed via a networked file system (NFS) mount. This issue does not affect Solaris or Linux platforms. |
Chandra/CIAO WorkshopsThe Chandra X-Ray Center (CXC) offers a series of workshops 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). CIAO 4.0, released in December 2007, will be used in the hands-on analysis sessions. The program includes talks on:
The hands-on sessions enable participants to gain experience using CIAO on Chandra data. Members of the CIAO team will be on hand at all times to solve problems. Sample Chandra data sets are provided, but attendees may choose to work with their own Chandra data. Information on past workshops - which includes electronic copies of all the handouts and presentations - may be found in the Previous Workshops webpages. Logistical Information for workshop attendees is available from the Travel & Lodging page. We also recommend some Preparation if you are planning on attending an upcoming workshop. If you are planning your own CIAO workshop and would like to request support from the CXC, please submit the relevant details to the Helpdesk. Proposals will be considered on a case-by-case basis. |
