excused:
ML Marco Leoni


next telecon:
Jan. 14, 2004, 3 GMT


notes:
- Ivo away from Jan. 8 - February 2
- added SWS support, reviewed error handling, 
  (ISO search by instrument?) to SpecView
- catalog format (PP)
- FORS spectra + catalog of GOODS (non-X-ray) sources should be available 
  by next week




new action items:
PP produce a short list of ACS tiles with interesting sources
PH check availability of JBO computers during 'Beagle 2 search'
AR to look into column manipulation issue
MA upload a complete VOTable version of the Alexander catalog to ExtragalacticScenario for testing and check how to deal with upper limits; 
   see (http://www.euro-vo.org/twiki/bin/view/Avo/ColumnManipulations)
   also, make sure that the "correct" default columns are put into Vizier
MD release full FORS SSA service replacing current CGI interface
MD provide GOODS FORS spectra in similar way as soon as available
Note that the actions concerning HyperZ/ACE/X-Corr are still ongoing


previous action items:
PR+PP provide samples of spectra with certain features (type 1 and 2)
Done.
There is an issue concerning the (visual) scaling of FORS spectra for which there is a non optimal workaround. Right now a change to a logarithmic scale is the best that can be done. 

PH write down Astrogrid part of workflow (separate from core AVO prototype)
ongoing. 

JH+PH+MA need to load ACS images into MySpace
ongoing. 
GOODS data arrived on 9 DVDs.

ML+FB 2x2 K or 4x4 K ACS cut-outs (instead of 1x1 K); make benchmark test between CDS & ESO
FB will provide 2x2 K cutouts starting early next week Jan. 12
ML will test 

NW is to supervise scientific validation of WP 3.2.4.1 and creation of initial redshifts by Jan. 19; that should include a comparison between photometric and spectroscopic redshifts 
ongoing.

PP Wiki page with math. equations for extragalactic case on-line
done.
http://www.euro-vo.org/twiki/bin/view/Avo/ColumnManipulations

MA+TL coordinate implementation of VOTable calculations
TL Topcat supports column manipulations
TB works on a lightweight column calculator in VOPlot; results are added as an additional column to catalog

TB cut new release of AVO prototype with latest Specview (SWS, colors, performance) 
done.

MD (re)circulate VOTable version of Szokoly catalogue as prepared by MA
done.

notes:
FB+AR working on raising visibility of Merlin+VLA data in the demo
MA suggests to start with CDFS sections 24 + 34 (in response to PH)

Please note that Ivo Busko will be away sometime tommorrow Jan. 8 until February 2. So, if you detect any problem with the Specview plug-in in AVO0.944 please shout immediately!!

Snippet from AVO minutes Dec. 17:
It was agreed to provide 3 items by Jan. 19, 2004:
1. catalogue of redshifts for objects covered by ACS GOODS fields
   MA will suggest particularly interesting tiles
2. release (at least within AVO) versions of ACE (MH), X-Corr (PO) and HyperZ (PH) which can be used to re-produce results of point 1
3. integrate ACE, X-Corr and HyperZ in an Astrogrid framework as outlined by PH
