Minutes for the terameeting of April 16th 2007

Present: Mireille, Chiara, Frederic, Gregory, Yannick, Henry, Emmanuel, Mathias (through videoconf)

Emmanuel's summary document

CFHTLS T04 processing
 Yannick will change the first 4 lines of his .reg files to WCS format. Henry will modify his checkpoly script to have it running with Yannick's .reg files.
 The release of QualityFITS is delayed. A deadline will be set by Friday.
 Fred will replace the USNO-B1 astrometric check with 2MASS (using the CDS server).
 Emmanuel will produce a new RPM for SCAMP before leaving on holiday (today).
 It should be possible to measure automatically the saturation level within SExtractor. Meanwhile, Fred should lower manually the SExtractor saturation level in QFITSout, based on what is seen in the "Wide" stacks.
 Bugs have been detected by Gregory on the latest PSFEx VOTable outputs. Emmanuel will fix them when he is back (next week).
 Mireille will check that the MEGACAM P.I. table is up to date.
 Yannick will change the paths of the T03 table so that the CADC can point to it. Deadline: April 25th.
 Mireille has noticed that the average skyprobe values have a tendency to shift towards higher absorption with time. Yannick will ask Jean-Charles about this problem.
 Henry and/or Mathias will provide the tool to introduce the E(B-V) in the final catalogs.
 We are still waiting for Jean-Charles's output concerning the MEGACAM ZP drift.
 Henry-Joy insists on the fact that "his" photometric selection is not very different from that of SPICA.
 Yannick will check with Frederic what needs to be changed in QFITS before restarting W1.
 One W4 stack will be put on the directory accessed by CADC for testing before Wednesday 25.
 Action summary (chronological):

• Restart the processing of W1 with 2MASS astrometric checks in QFITSout (Fred),
• Produce updated W4 .ahead files (Henry),
• Remove the current W4 results (data+DB entries),
• Start again W4 with updated W4 .ahead files and 2MASS astrometric checks in QFITSout (Fred),
• Create the .ahead and .head files for Deep 25% best seeing exposures (Henry),
• Start processing of Deep 25% (Fred),
• Start the correction of lower case exponents in weight-maps and the transfer to CADC (Fred),
• Understand why during the W4 run some chi2 and colour images were missing.

WIRCAM processing
 Henry has recovered his passwd in Hawaii and must check the config files there before rerunning the script. He will try to do it before next Tuesday.
 Loic has asked for Chiara's masking recipe. Chiara has sent it and is waiting for feedback.
 The Monin data have been reprocessed; Chiara is still waiting for the Y-band zero-points.
 Chiara asks whether The QFITS implementation at CFHT will be available for WIRCAM data. Yannick thinks so; we will check when Loic comes during the 3rd week of May.

Miscellaneous
 Yannick has not received any official request from Mario/LBT yet.
 Emmanuel asks Fred whether he could install the latest Valgrind version of cluster machines. Mix3 is also missing ForkManager.

Next terameeting: probably Monday April 23rd
