Minutes of WFCAM Science Archive meeting:       20th May 2005
-------------------------------------------------------------
-------------------------------------------------------------

Present:       NCH, NJC, ETWS, MAR
Apologies:     MCH, AL, RGM, JPE, PMW, JDT, JM

DONM: 10am, Friday 20th May 2005, plate library


Actions discharged:
-------------------

ACTION: NCH to write a tutorial on how to query cross-matched data in the
        WSA for the web pages.
Discharged; completed doc being perused by the team before being put on the
web site.


Actions partly discharged but continuing:
-----------------------------------------

ACTION: MAR to flesh out the "Data Overview" web pages for the WSA.
Work in progress.


Actions carried forward from  6/05/05 meeting:
----------------------------------------------

None this week.


Specific points and new actions:
--------------------------------

Project management:

Nothing new this week.


WFCAM update:

Nothing new to report.


Comments and issues arising from CASU fortnightly minutes:

The team noted the minutes of the meeting of 17/5/2005.


Networking:

Nothing new this week.


Hardware:

All archive hardware are functioning normally.


Software:

NCH noted some scaling problems with large volume catalogue joins (CU16)
through the curation client/ DBMS load server ODBC connection (there are
problems with high volumes of transaction logging, and difficulties with
execution of multiple-statement batches on the server via ODBC). Temporary
workarounds have been set up for the time being; advice will be sought
from experts within Microsoft and JHU to find more permanent solutions.

MAR has continued work on user query queueing; ETWS has completed work
on CU5 (default difference image products) and this needs to be tested
with the newly processed phase-I commissioning data; NJC continues to
work on the core numerical routines required for CU8 (global photometric
recalibration).


Data Release:

NCH suggested that it would be good if we can get the newly processed
phase-I commissioning data released to the UKIDSS Testers community
before the UKIRT Board meeting on Thurs 26th. NCH will look after the
catalogue cross-matching; MAR the web documentation; ETWS transfer/ingest
and NJC will peruse the web site and docs and suggest any modifications.


SSA:

Nothing new this week


Astrogrid deployment:

No news this week.


Miscellaneous:

NCH noted that the topic of this year's Annual ROE workshop was now pretty
much fixed as "Panoramic near-IR astronomy" and it is envisaged that there
will be a significant chunk devoted to WFCAM/UKIDSS/VISTA. Provisional
dates are somewhere late Oct/ early Nov.

ETWS and MAR noted that there was as yet no programme available for the
Euro-VO workshop in Germany; and that there is also an AstroGrid workshop
in Cambridge.
