3rd September 2008 APM comfy chairs 11:30-12:55 Present: RWA, MJI, JRL, PSB, MR, DWE, EGS, STH, RGM Apologies: NAW Agenda ------ 1. Actions from last meeting 2. Comments on WFAU minutes 3. Recent and upcoming meetings - ESO SADT+P2PP, VOTC, ADASS 4. Data archives update - AAT, ING, WFCAM, UKIRT 5. Optical/NIR processing - VST news 6. WFCAM update - general news, reprocessing, bad pixel masks, pipeline updates 08B 7. VISTA update - general news, report on vircam data, status of calib frames and science data, SV programme, hardware, software 8. AOB Minutes ------- 1. Actions from last meeting STH has not finished checking that the Plone astrometry technical pages are correct - ongoing <<<< (reminder - this was originally from 080332 - see those minutes for further details) STH has not included the graphic showing the size of the photometric radial distortion correction in the Plone technical pages - ongoing <<<< He will also update the photometry pages to account for new things from the photometric calibration paper. MJI has ordered some suitable tables for the meeting area, but delivery will take 4 weeks! JRL has not produced a web page of HawkI publicity for CASU - ongoing <<<< MR has not installed JRL's script to flag summit-rejected MSBs during raw WFCAM data ingestion - ongoing <<<< It was noted that the deadline for this was 15 September. ALL considered submission of abstracts for ADASS 2008. MJI and NAW have submitted abstracts. RWA has removed the JKT CD ROMs from the computer room and rationalized the storage to free up a cabinet. Many backups of this data exist. EGS implemented a backup scheme for internet transferred INT/WHT data and switch to LTO4 tapes PSB ordered the LTO4 tapes needed for the above action RWA moved the 08A WFCAM raw data backup tapes to the Observatory building store cupboard MJI has discussed topics and suitable time/date for telecon with JAC, but has not received a response. This is needed before WFCAM goes back on. MJI will continue proddling - ongoing <<<< JRL has not made minor changes to object masking sky estimation strategy MJI have come up with a plan for software release. This will be from the EGS Plone pages and will be located at http://casu.ast.cam.ac.uk/surveys-projects/software-release At the moment this is in draft form so not accessible to the outside world yet. (EGS and MJI will continue working on these pages <<<<) (Do you want this action to finish these pages?) 2. Comments on WFAU minutes None 3. Recent and upcoming meetings EGS will write the presentation for the SADT+P2PP meeting at ESO. MJI's <<<< recent Leiden presentation can be used as a starting point. It was stressed that the use of FTP transfer should be heavily plugged during this presentation. It is also necessary to raise the issue of why you need offset skies. An example from WFCAM can be found to show why sky subtraction is important (or VISTA chip 16). PSB said that he would help STH prepare for his VISTA observing run by demonstrating the simulator so that he would have some idea of how to observe with VISTA. <<<< STH said that he would need a list of suitable targets to observe. <<<< Calibrations will be a high priority. JRL said that many observations did not have enough darks. JRL and MR have been volunteered to attend the VOTC meeting in Cambridge (25 & 26 September). <<<< 4. Data archives update 5. Optical/NIR processing 6. WFCAM update STH said that the photometric calibration paper had been submitted. Many people fell off their chairs at this news and had to be revived. STH was asked to make the paper available on the Plone site. <<<< In light of this startling news, MJI said that he would try and finish off the technical paper. <<<< JRL will look into the mottled sky problem. The data for this was taken on 21 May. <<<< (not sure I've got this right) MJI said that he would look into the bad pixel map issue of WFCAM (what data is needed in addition to the confidence maps). <<<< 7. VISTA update PSB said that it was a pain in the neck that evening meals cannot be a bit flexible so that evening twilight flats can be taken. MJI said that he would find out how CASU could get access to the VISTA SV data. <<<< Information on the VISTA SV data can be found at http://www.ast.cam.ac.uk/~wfcam/internal/vista/sv/ PSB will check to see if the new machines' power consumption is regulated. <<<< Temperature monitoring (and other things can be found at http://ioadpc.ast.cam.ac.uk/mrtg/ for Gaia and http://www.ast.cam.ac.uk/mrtg-apm/ for apm29 8. AOB Continuing actions ------------------ STH check that Plone astrometry technical pages are correct STH include graphic showing the size of the photometric radial distortion correction in the Plone technical pages.
