@AVO Telecon: Nov. 26, 03

participants:
MA Mark Allen
TB Thomas Boch
LC Laurent Cambresy
SB Sebastien Derriere
ML Marco Leoni
PO Patricio Ortiz
AR Anita Richards
PR Piero Rosati


chair:
PP Paolo Padovani


excused:
NW Nicholas Walton


minutes:
MD Markus Dolensky, revised by PP


next telecon:
Wed, Dec. 3, 3 GMT


new action items:
TB contact Ivo in order to retrofit ISO specific code changes into Specview
PP invite Alberto Salama to project meeting
PO agree on xmatch interface within Astrogrid and then with CDS


previous action items:
AR find tester for proxy configuration feature
Nobody with problems found within Astrogrid community ;-)

PP+AR provide CDS with info on necessary catalogues for inclusion in Vizier
closed.

TB implement way to load specview log into VOPlot
ongoing.

MA using the new AVO prototype check which ISO spectra do or do not work with specview 
ongoing.

MD+PP correct minutes of last telecon to explicity state that FG is to be kept informed 
about plans for the cross matcher closed.

ALL provide AR with ideas and feedback on galactic scenarios
Main point: How to use ISO spectra. 
closed.

ALL inform MD+PP by the end of this week if there is a need to arrange for extra technical 
meetings at the AVO Project meeting at ESO on Wednesday Dec. 10. 
closed. Nobody requested additional topics requiring an extra day.



extragalactic case:
http://www.euro-vo.org/twiki/bin/view/Avo/ExtragalacticScenario

PO takes care of implementation of cross correlation service
http://www.euro-vo.org/twiki/bin/view/Avo/GeomXMatch

SB and PO both report that VOTable I/O is the most time consuming part
of xmatcher. For big datasets the network bandwidth limits efficency,
but this is not an issue for the small tables in the given scenario.
MA clarification: The output is a join of both input tables and we
need be careful not to confuse resulting duplicate column names.  - we
need to keep track of mismatches
PP+PO discuss how to implement additional column describing the quality of match


galactic case:
http://www.euro-vo.org/twiki/bin/view/Avo/GalacticScenario

AR In contact with Matteo Guainazzi regarding XMM data
The complexity of the structure of ISO spectra pushes the current
software to its limits.
TB made some ad hoc modifications which need to be retrofitted into
the Specview baseline version.
MA+AR sorted out issue about which ISO products to use. In the past
week there was some debate about how far to go in terms of scientific
analysis based on given data products and software tools. Therefore,
Alberto Salama should be invited to project meeting.


Registry:
SD released OAI registry interface to Vizier and seeks feedback
http://www.ivoa.net/forum/registry/0776.htm
AR mentions Noel Winstanley <nw@@jb.man.ac.uk> as somebody possibly
interested in this development.
