Minutes 29 june 2004 OmegaCEN NL - team - Quarterly
Review Meeting
Present: EV, ED, EH, DB, PH, MT,
KGB, RV
Main Actions for the team in
the coming quarter
AI DB/EH/EV 06/29
Prepare db interface version of the
User and Programmers Manual
AI KGB/DB 04/29
Prepare report on performance and end
user documentation of sAssociate.
Include some use cases and provide
simple scripts for these cases.
Ingest USNO Naval catalog into
Oracle10g for performance/scalability tests.
Prepare report for CWI db meeting
early september and for G(A(VO)) collaboration
Quality control developments
AI All 06/29
New section(s) "cookbook descriptions
of the various quality controls" must be added
to the Manual.tex in a seperate section in Manual.tex dedicated to QC.
Sub-Sections should include
- overall pipeline end-to-end check
(EH)
- flatfield qc (EH)
- photom qc (RV)
- astrom qc (ED)
- tutti frutti qc (EH)
AI EH 01/23
Verify
astrometry/regridding/coaddition of pipeline by applying the seeing/psf
method.
This is for image pipeline end-to-end check. Apply to demo data.
Object viewer/ User
interface/ VO
It was decided to further expand the experimental Object viewer made by
Michiel and to eventually develop it into different frames which show
the underlying datastructures belonging to the different pipelines
(image pipeline, photom pipeline, flat field pipeline, tutti frutti
pipeline).
In this view Object viewer will facilitate:
- user interface for QC - viewing what is there- what has been
processed, is available etc
- allows to follow the links to the objects used for deriving the
results
- what is the quality of the data by inspecting the proper
attributes (filtered in the frames), or clicking on the objects
themselves, triggering image views or table inspections
- usage of db toolbox
- change time stamps
- check availble data for given time
- obeys context parameters
AI MT + DB + KGB 06/29
- make inventory of needed
functionalities
- make implemantion plan
- install a simple basic test version to be used by others early
september
Astrometry -QC
AI ED 06/29
- Put QC parameters of LDAC
astrometry in pipeline; insert quality flags
- write section for cookbook
- make proposal for global (multi chip) astronomical solution
Flat field - QC
AI EH 06/29
Make Python QC scripts using statistics
in windows for QC usuable for ff, bias, science frames etc
AI EH 06/29
Add check on background determination
by Sextractor
Photometry - QC
AI RV 06/29
- Put in manual.tex the description of
extinction report etc
- add descriptions of zeropoint QC, compare etc and residual plots -
all in Manual.tex QC section
- complete photometric pipeline doc.
AI RV PH 06/29
- complete secondary standard report
(with error analysis) and prepare this for scientific publication
DATA BASE Issues
Coming quarter we will focus on the implementation of the planned
context/authorisation mechanism. This is a very important step in
the Awe db development and when combined with the federation mechanism
will lead to the eventual information system.
AI DB 06/29
- make outline + test implementation
linking global context parameters as set in Python (Awe prompt) to
subsections/authorization of the db
- ask Oracle for advise
- check out federation developments (STREAMS vs Advance
replication in 10g)
Action items
AI EV 06/29
Complete PAE
with ESO
AI KGB, MT, EV 06/29
Define the GAVO VO functionality
for matching Awe tables with SDSS, XMM and ROSAT catalogues
AI DB 06/29
Inform the rest of the "community"
about the changes made in the ingest
procedure.
AI KGB/DB 04/16
Migrate the system from Oracle9i to
Oracle10g. Check the proper
functioning of the SourceList/AssociateList machinery under the new
database.
AI KGB 06/29
Update 04/29 : migration to and use of
Oracle10g needs more powerful hardware.
AI KGB/DB 04/29
Investigate the hardware requirements
for building an RAC (Real Application Cluster) node.
AI EH/EV 06/29
Make a 'snag it' version of the AW
demo.
AI EH 06/29
Contact M. Radovich about the quality
of the astrometry.
AI MT/DB/?? 01/23
Investigate Gobi, VTK and get in touch
with Frans van Hoesel.
Closed action items
AI DB 06/16
Plan a team-meeting to be held at the
end of june (make sure ED is there too).
AI RV/EV 04/16
Make progress report secondary
standards, including a break-down of
the error budget.
AI EH 06/16
Check out the status of the
flatfielding QC tools as delivered by OAC.
AI EH/DB 06/16
Improve ingest procedure and make
ingestion of data possible for users.
Document the ingest procedure in Manual.
