From nch@roe.ac.uk Fri Apr 29 11:44:32 2005 Date: Fri, 29 Apr 2005 11:30:05 +0100 (BST) From: Nigel Hambly To: WFCAM Science Archive Team -- Eckhard Sutorius , Mike Read , Nigel Hambly , Nicholas Cross , Bob Mann Cc: CCs for WSA weekly meeting minutes distribution -- Andrew Lawrence , Andy Adamson , John Taylor , Jim Emerson , Malcolm Stewart , Martin Hill , Mike Irwin , Peredur Williams , Stephen Warren Subject: WFAU WSA weekly meeting minutes: 29th April 2005 Minutes of WFCAM Science Archive meeting: 29th April 2005 ------------------------------------------------------------- ------------------------------------------------------------- Present: NCH, NJC, AL, JMS, MAR, ETWS Apologies: MCH, PMW, JPE, RGM DONM: 10am, Friday 6th May 2005, plate library Actions discharged: ------------------- ACTION: MAR & NCH to check out SQL Server networked server functionality for cross-server querying. Discharged: seems to work well, but no bench marking has been done yet owing to time constraints. ACTION: NCH to contact Jan at JHU to enquire as to possible net transfer of the next SDSS catalogue access release database(s). Discharged: DR3 will be copied over within the next few weeks. See Networking below. Actions partly discharged but continuing: ----------------------------------------- ACTION: ETWS to look into 3dm RAID monitoring on sneferu, along the lines of the browsable pages on djoser. Continues: helpdesk ticket in so this is now in the hands of HME. Actions carried forward from 15/04/05 meeting: ---------------------------------------------- ACTION: NCH to write a tutorial on how to query cross-matched data in the WSA for the web pages. - CONTINUES Specific points and new actions: -------------------------------- Project management: JMS noted next week's VDMT meeting. According to Perry's wall chart, he will be back from holiday on Monday, and it is assumed that he will prepare the usual set of documents for the meeting. WFCAM update: Science verification time has been extended to allow all UKIDSS SV MSBs to be observed. AL noted that there are reports from the science verification observing team, linked from a new UKIDSS science verification Wiki site available at http://wiki.astrogrid.org/bin/view/UKIDSS/SciVer. This has been linked from the WSA TWiki pages. Comments and issues arising from CASU fortnightly minutes: The team noted the minutes of the meeting of 18th April 2005; ETWS also expressed caution over the putative timescale for processing and release of science verification data products expected by the consortium following the UKIDSS science verification meeting (see link above). Depending on outstanding issues from shake-down using commissioning data, the required timescale from ingest to release may be longer than one week. NCH suggested that it should not be longer than two weeks; and this is what was stated at the science verification meeting. Networking: NCH noted that Jan Vandenberg at JHU is kindly making available a set of backup files of the SDSS DR3 catalogue access DB; this will be copied over to WFAU when Jan gives the go-ahead. NCH also noted that disk space is becoming a bit tight on the public DB server, and asked the team for opinions on whether previous releases of SDSS should be maintained, given that each new release supersedes previous ones, and that all releases are maintained at the JHU servers anyway. The consensus seemed to be that as long as no users have made heavy science use of a given SDSS DR at WFAU, then there is no need to keep online old DRs on our archive server. Hardware: All archive hardware continues to function normally, apart from a small glitch in operation of the load server on Monday evening following the inexplicable turning off of an air conditioning unit in C1 at some point on Monday by an unknown b*****d. Software: ETWS noted that CU4 (catalogue ingest) is now working well, based on the latest pipeline processed catalogues from CASU. NJC noted that the CU8 documentation is being drafted and he anticipated distributing a draft early next week; NCH suggested that STH from CASU should be in the loop on the archive global photometric calibration in a consultative role, and asked that NJC includes him in any document distribution. MAR noted new enhancements to the user interface codes; the UKIDSS Tester community has been updated on the basis of Steve Warren's new list; and finally that he is working on web applications for an administrative interface for community contacts to maintain the full-blown community access (projected completion within a week or so). Data Release: No further news this week SSA: Nothing new this week Astrogrid deployment: No news this week. Miscellaneous: AL noted that Nick Kaiser (PanStarrs boss) is likely to be visiting in June; he is interested in learning about VDFS processing/archiving software. At the moment, it looks like June 21-24 is the likely time slot.
