1.  Updated Observation Visualizer (ObsVis) Tool

2.  Radio Galaxies in the Chandra Era



Item 1.  Updated Observation Visualizer (ObsVis) Tool

ObsVis is a tool to aid in observation planning which allows the
inspection of sky images with overlaid instrument fields-of-view
(FoV). ObsVis interfaces with the SAOimage DS9 image display tool, and 
facilitates detailed manipulation of Chandra pointing and instrument

ObsVis was updated in Dec 2007 with the CIAO4.0 release.
With the latest release Feb 2008 (part of CIAO4.0.1), several minor bugs
were fixed, and features added.  ObsVis can now display multiple
Chandra FoVs on a sky image, which can be grouped in a variety of
ways.  ObsVis can also generate an evenly-spaced grid of pointings on
the sky. FoVs can be saved to a file for later reloading. 

A quick ObsVis primer page is available at
with a more detailed manual at

ObsVis runs either as a standalone package, or as part of CIAO.
The standalone package can be downloaded from
If you already have CIAO 4.0 installed, you should download
the ObsVis 4.0.1 patch from the  CIAO download page.
