Details of the meeting:

Data release
-  current state: QualityFITS pipeline is currently running, SPICA is waiting for Qfits input that feed DBSpica and DBterapix prior to continue the T0002 release process.
-  expected release date: 01/15/05

ICD status
-  Frederic is about to read it. He will send comments to Yannick.

Scamp
-  current version: 0.42-MP
-  current version release date : 12/18/04
-  current status: 0.42-MP Running on T0002
-  current work:
- Test with catalogs UCAC1 and UCAC2. Sources found but pattern matching is not good.
- Successful tests with 2MASS, GSC-2.2 and GSC-1.3 catalogs. DENIS catalog can be used also.
- Scamp will be tested with 2-MASS catalog on z-band with Dougados data by Yannick.
- Scamp now supports an external file (FITS ldac) as a catalog. It is used for astrometric references (see scamp -d). Scamp is able to load best catalogs in a set for each part of the sky and to save obtained local catalogs.
- Default parameters have changed: XWIN_IMAG, YWIN_IMAG. Yannick will modify the ICD accordingly.
-  next release date: before end of December 2004, with MAG_PETRO keyword and threshold option for T0002.
-  new queries:
- Add threshold parameter
- Possibility to work on a given focal plan
- Possibility to choose photometric parameters
- Possibility to select a limited number of sources as input data
- Documentation after T0002 release

QFits
-  current version: not released
-  current version release date : -
-  current status: Running on T0002
-  current work:
- Write documentation and configure a package to compile the software. PLPLOT and CFITSIO included because we used terapix-patched versions.
-  next release date: First week of January 2005
-  new queries:

Defectix
-  current version: 0.9.1
-  current version release date: 12/27/04
-  current status: Coding and testing A version is installed on mix1 and is currently being tested by Yannick.
-  current work:
-  next release date: January 2005
-  new queries:
- Treatment parallelisation while computing masks.
- Possibility to load simple FITS images (not MEF)
- Code a defectix -d to display a default configuration file.
- libccgnu2 should be installed on mix1,4 (Frederic and Anthony)
- Time estimation (Yannick and Anthony)
- Think about masks format compared to bit masks (All)
- Enhance simulators
- Create a list of images with unusual defects from new QFits-ed images (Yannick, Mireille)

Subversion
-  current state: version 1.0.8 installed on terapix (backport: stable on woody)
-  queries: - Configure for next week (Anthony, Gilles, Frederic)
- Study O'reilly online book
- Write a howto for Terapix users
- Remove CVS (Gilles)

Hardware
-  current issues:
Mix4 stability problems

-  current works:
Backuping disks of DIGITAL computers. Not enough bands to store everything. Top priority: at least on full backup done on tapes.

-  solved problems:
- Mix4: Uninstallation of the USB2 module and testing Mix4 again did not solve the problem; so it has been installed again.
Problem located, a RAM was defective and removed. Mix4 seems stable since then (memtester is OK). The RAM should be send back for an exchange. Mix4 will be kept out of the cluster for a while to check its stability, test defectix and compute several post processing tasks. Later (likely after T0002), it would be better to have Mix4 in and Mix2 out. This solution must be discussed with Laurent.

-  new queries:
- There will soon be no more place to install new computers. This problem should be considered after T0002 release.
- DIGITAL computers must be cleaned before backup. Gilles will ask people to do so. DIGITAL computers will be removed from TERAPIX network before the third week of january 2005.
- FTP terapix.
- Need an web page showing where data are archived (band number, band location...) or how to find data. (Gilles)
- Installation of new computers during january 2005.
- Pix10 is totally useless. It should be installed in the CFHTLS-cosmix cluster. CPU will be available for users and disks will be kept for terapix backups only. According to Frederic, it could be done in 10 minutes. Should the installation take more than 10mn, Yannick suggests to give up, as suggested earlier by Emmanuel, and leave pix10 on the Terapixcluster.
- Test shutdown after T0002.
