*********

notes:

I) Extragalactic case:
http://www.euro-vo.org/twiki/bin/view/Avo/ExtragalacticScenario

Almost all data/catalogs are, or will soon be, available.  

PR is working on FORS2 spectra, creating a table mapping the 
X-ray catalog with FORS2 spectra filenames; should be done by Friday. 

MD brought up the issue of how to x-match optical/X-ray sources; this
started a long discussion on the more general problem of cross-
correlating catalogs in a VO environment, taking into account the
positional uncertainties. Also, the related problem of image 
registration was addressed. 

PR reports that optical sources have been already identified in a  
given field

NW opts for a general solution using the Astrogrid infrastructure and 
by implementing a specific service that joins two tables.

A few technical requirements, currently not implemented, came up.
MD will collate and circulate them. 

II) Galactic case:
http://www.euro-vo.org/twiki/bin/view/Avo/GalacticScenario
new page
http://www.euro-vo.org/twiki/bin/view/Avo/GalacticRequirements

AR: use of the GLIMPSE survey is being investigated; also, the
internationl Galactic Plane Survey is being incorporated in Aladdin 
and Vizier; this will require CADC support

Latest Specview improvements:
- see http://www.euro-vo.org/twiki/bin/view/Avo/UsingSpecview
- successfuly tested HTTP GET access from ESO for sample spectra with 
the new Specview plug-in
