Minutes for the terameeting for Feb. February 7th 2006

Present: Yannick, Emmanuel, Anis, Jean-Christophe, Fred, Henry Anthony, Chiara, Mathias

PI DATA
 MEGACAM: 03BH98 Tully data have been Qfits-ed and graded; Mireille is running SCAMP/Swarp/etc..; u* observations causes problems
 MEGACAM: Still waiting to receive the Dougados 04BF28 data from CADC
 WIRCAM: Sanders data has been taken and are at the CFHT; we are awaiting CFHT to complete the pre-processing processing,
 WIRCAM: Fouchez data, same status as Sanders
 WIRCAM: Cuby, Henry producing catalogues using visible+NIR data. Will deliver them to Jean-Gabriel. Yannick ask Henry to keep Chiara and Yannick informed on any progress.

T0003-WIDE (Yannick, Mathias, Henry)
 Mathias has made comparisons between the CFHTLS and the SDSS;
 Mathias will provide some text concerning his comparison to be provided on the web-pages
 One problem is that for the u* and z* filters obtained so far are in the W1 area, so there is no overlap with the Sloan. In the overlap area, only r,g and i data are available.
 CADC have been informed that we would like to provide the wide data to the community on the 14th Feb.

Table-T0003
 Apparently the T0003 table is not ready because of a problem with file permissions
 Yannick will produce a manual version of the table if no-one is able to sort out these problems by Friday

V0003 (Emmanuel, Yannick)

 According to Emmanuel the megacam.ahead is ready and we can re-start the processing for the very-wide data

 Note that the Scamp configuration file has to be changed; POSANGLE_MAXERR et MATCH_NMAX need to be changed
 Emmanuel will provide a new bug-fix release version of Scamp
 currently, only around 30% of the fields are unusable;
 In the re-processing of the very-wide we will add another machine (mix6,mix3 and mix4 in total); should take around 20 days (hopefully)

Webservice QFits (Jean-Christophe)
 A bug was found in the service which is triggered when a '+' sign is present in the input image filename; this has been fixed

 Emmanuel will provide some WFI images to test the service; Mathias will also try to test the service remotely from Besancon, tests have to be done with WIRCAM, FORS, MEGACAM MEF and stacks, CFHT12k stacks
 Webservice will be made public before Feb. 14.

Visualisation tool (Anis)
 Some tests made with the OpenVidia programming library which may allow acceleration for large images
 However, for no FITS images have been displayed
 Anis will will try with a small FITS image of 256x256 and the shader library to see if this image can be displayed as a FEASIBILITY study. Goal: have a FITS image displayed by Friday.

Other stuff
 2MASS catalogue has been installed locally
 Laurent will modify aclientTerapix.pl used by Scamp so that this catalogue is called during processing
 Yannick asks everyone to send him which dates they are available in the February - March time-frame for discussions concerning the processing of T0004.

Hardware

 Enough credits to order two machines like mix7. Goal: having mix8+mix9 and a fcix2 out/in disks by June 2006 in the cluster. Emmanuel will order an Efigix.
 The process will be started probably at the start of march; so they are ready for June, at least three months before T0004
 Need to check that there is enough electricity available!
