Item 1.  Chandra Source Catalog Information
===========================================


Information about the Chandra Source Catalog project, including the
catalog requirements and associated documents, is now available on
the CXC web site at the following URL:

http://cxc.cfa.harvard.edu/csc

The catalog web site will be updated regularly as we approach
catalog production and release.

For those who are unfamiliar with the project, the Chandra Source
Catalog will be the definitive catalog of all X-ray sources detected
by the Chandra X-ray Observatory.  The catalog will include fields of
all Galactic latitudes, and sources from the entire detector field of
view, although the first catalog release will be restricted to imaging
data only.

Item 2.  Goddard Email
======================


Goddard Scientists:  If your email is changing, please 
use our webpage to provide us with your new email:

http://cxc.harvard.edu/cdo/udb/userdat.html

Of course, we request that anyone with new contact 
information do the same to keep our lists up to date.

Thanks all.

Item 3.  MARX 4.3 is now available  
==================================


MARX is a raytrace program that allows a user to simulate the
on-orbit performance of the Chandra X-ray Observatory for variety of
astrophysical sources.  It can output Chandra EVENT files that may be
processed using standard CIAO tools.  Version 4.3 contains calibration
updates, support for large files, and has been ported to Cygwin and
MacOSX.  The examples on the MARX web pages have been rewritten to
reflect the changes in both MARX 4.3 and the CIAO 4 tools.  See
http://space.mit.edu/cxc/marx/ for more information.

                           COSPAR SESSION E11

                       to be held as part of the
                    37th COSPAR Scientific Assembly
                     Montreal, Canada, July 13-20, 2008

-------------------------------------------------------------------------------

In recent years, we have seen tremendous progress in the field of neutron star 
research, primarily enabled by multi-wavelength timing, imaging and 
spectroscopic observations with both ground and space-based observatories. 
Along with ground-based radio, optical and infra-red telescopes, an array of 
X-ray and Gamma ray observatories -- such as RXTE, INTEGRAL, Chandra, 
XMM-Newton and SWIFT -- with broad ranging timing, spectral and imaging 
capabilities has opened a new era of multi-wavelength investigations. 
Multi-wavelength observations of the different manifestations of neutron 
stars like radio pulsars, magnetars, isolated neutron stars etc. offer the 
opportunity to investigate a wide range of astrophysical problems including 
the extremes of gravity, density and magnetic field. At the COSPAR assembly 
in Montreal, 2008, we will have an opportunity to bring together researchers 
from diverse fields and gauge the direction of future neutron star research 
with
existing and coming observatories, such as GLAST and ASTROSAT.

We invite you to participate in this meeting and to submit abstracts for
contributed talks or posters via the COSPAR assembly website
http://www.cospar-assembly.org/

Item 5.  Chandra Deep Field South: Merged Products for 2000 and 2007 
Observations
===============================================================================
==


The old 2000 and the new 2007 data from the Chandra Deep Field South
have been custom processed to register all 21 individual observations
astrometrically. For more information, see:

	http://cxc.harvard.edu/cda/whatsnew.html#CDFS2000-2007

This web page provides several download files for three merged sets -
2000 only, 2007 only, and 2000+2007:

    * Tar file containing the merged event file, exposure map, and image 
    * By-ObsId tar file containing the event list and aspect solution
        for each of the individual ObsIds
    * Full resolution linear three-color image of merged datasets
    * Full resolution enhanced three-color image of merged datasets
    * Smoothed enhanced three-color image of merged datasets
