Item 1: X-ray Visionary Projects (XVPs): Notice of Intent Reminder

All PIs planning to submit an XVP proposal are asked to submit a
Notice of Intent to the CXC Helpdesk ( by
21 Jan 2011. The Notice of Intent should include: PI name, Title,
Estimated exposure time, preliminary list of co-Is, brief
abstract. For more information please refer to the Cycle 13 Call for
Proposal Section 4.3.

Item 2: Chandra Data Archive Footprint Service

There is a new interface to the Chandra Data Archive (CDA): the
Chandra Data Archive Footprint Service (CDAFS), modeled after the
footprint service of the Hubble Legacy Archive (HLA). 

The CDAFS provides a visual web interface to all public Chandra
observations and to the observational data used for the current
version of the Chandra Source Catalog (CSC). 

The web page contains tabs for three main views of the CDA:
 - Footprints
 - Image Inventory
 - Preview Images/Download Data

On the (main) Footprint tab the instrumental sky coverage (color-coded
by instrument) is superimposed on an image from the Digital Sky
Survey. This graphical representation is complemented by a
configurable table with metadata on the observations that are
represented in the footprint view. The other tabs provide access to
Chandra images (through the SIAP interface) and a seamless interface
to WebChaSeR for downloading data. User selections are maintained
between the tabs. The contents of the page are also available in
VOTable format, using an IVOA-compliant footprint description. 

The CDAFS is available from:

The tool is especially useful for visual browsing of the CDA in
particular areas on the sky and for checking the CSC's sky
coverage. We emphasize that only *public* observations are presented
by the service. The CSC footprints are, of course, a subset of the
full public CDA footprints.
