Minutes
-------
1. Actions from last meeting
WJS has sent the current best estimates of the VISTA saturation limits
to STH.
STH has filled in the gaps of the photometric standard fields plan and
added a few more fields to the North of VISTA's zenith. This still
needs to be propagated into the Calibration Plan (by Monday). <<<<
DWE suggested that the appropriate declinations for the latitude of
WFCAM and VISTA be marked on the plot. STH said that he would do this.<<<<
STH has made no progress regarding the spatial systematics in the UFTI
standards data and new test data - ongoing <<<<
JRL has reached agreement with Adam and Benoit regarding the WFCAM example
FITS headers and files. A link to this has been added to our diary web
page (http://www.ast.cam.ac.uk/~wfcam/docs/wfcam_head_eso.ps).
MJI no progress on comparison of FIRES project reduced data with
ours - ongoing <<<<
STH has not calibrated FIRES data using NICMOS or the published FIRES work
- ongoing <<<<
STH has acquired the missing ISAAC data, but forgot to email its location
to JRL (!). STH to email JRL <<<<
JRL writing a report on ISAAC reductions is ongoing <<<<
MJI
JRL example calibration frames to test the ingest procedure have been
MJI sent to IAB.
ALL no comments on Paul Hirst's User Guide have been received by JRL
(understandable considering the preparation for the VISTA DFS PDR).
There will be a JAC telecon on Monday evening, so comments by then <<<<
would be useful. Some quick comments that were raised were the lack
of a link to the glossary and a simple printable (eg. ps or pdf)
version of the entire User Guide. It might also be useful to have
link to the MSB guideline page. [After the meeting MJI checked up
and found 7.1 was a pointer to the glossary and 7.2 to the MSB
guidelines.]
ALL had read the Data Reduction Specification and the User Requirements
Document and provided feedback for the 25th March meeting.
ALL had read V0.4 of the VISTA DFS UK User Requirements Document and some
comments had been passed onto WJS. This was felt to be an ongoing
action since there was a need to discuss this with WJS at the next
meeting. <<<<
DWE provided a document number for VISTA DFS UK User Requirements Document
2. Comments on WFAU minutes
MJI noted that WFAU were still having problems with their advanced disk
RAID array.
There was some discussion as to what picture format was most appropriate
(JPEG, GIF or PNG). It was noted that CASU generate PNG files in
their pseudo-colour image generating software.
3. Report on JAC telecons etc.
(inc. WFCAM User Guide, MSB guidelines)
There have been no JAC telecons since the last CASU meeting. The one
scheduled for 23rd March was cancelled. The next one will be on Monday
evening (5th April). STH said he may attend.
MJI said that the delayed disussion of issues relating to the WFCAM User
Guide will be raised at this meeting and that everyone should forward
any further comments to MJI by Monday. <<<<
Another issue was the status of the MSB guidelines and their use by
the survey heads in the UKIDSS consortium. The last information on this
is now 2 months old.
MJI and JRL were reminded to enquire about the status of the engineering
tests and the SDF example file.
4. Items for Q1 2004 report
There has been considerable progress on the VISTA documentation front
required for the DFS PDR (WP2) ie. the Calibration Plan, User Requirements
(ESO) and Data Reduction Specification documents. Over the last month
this has occupied the majority of the group's time. Final versions
for proof reading by DWE are needed by first thing Wednesday morning.
There will be further iterations of these available in plenty of time for
the upcoming telecon on Tuesday afternoon.
There had been some pleasing progress on the PSF generating and fitting
front. Several anticipated issues have been raised and factored in
for the next stage of development.
STH commented that overall most areas where there was a lack of progress
or slippage behind schedule, were due to the dearth of detailed engineering
data (understandable given the problems with the detectors).
The remaining items for the report need to be sent to STH as soon as
possible. <<<<
5. Work plan for Q2 2004
Although some future work plans had been sent to STH the detail of the Q2
deliverables still needs to be worked out. MJI and STH will go over the
GANTT charts etc. over the weekend and formulate a plan for Q2. This has
to be ready before 2:30pm Monday (5th April), when the next VDMT telecon
is to be held. <<<<
6. VDFS UK User Requirements Document v0.4
It was agreed that more feedback needs to be given to WJS regarding the VDFS
UK User Requirements Document. In order to do this we will arrange the next
CASU meeting so that WJS can attend. The deferred discussion of this
document will be the one of the main agenda items.
7. Outstanding PDR issues
There was a general discussion regarding the VISTA DFS project and the
science goals. Some worries were expressed that the science wood was
sometimes being lost in the engineering trees. It was noted that many
things of a general nature have been raised while preparing for this PDR
that have not been picked up at the previous reviews. It was felt that
VDUC could be very useful in helping to minimise this problem in the
future.
MJI reported that he had spoken with Tim Naylor (VDUC chair) at NAM2004 and
impressed upon him the need for VDUC to meet as soon as possible.
PSB said that the three PDR documents were now only being sent out for
review as PDF files, so that the problem of multiple word doc copies of the
same document would not arise again. This had wasted a lot of time over
the last two weeks, refixing formats, typos and so on. He also reported
that with JMS's help he has even managed to get digital signatures to work.
8. AOB:
APM building refurbishment
MJI said that the APM building refurbishment is still on track.
[ STH :-) PSB :-( but watch this space ]. The plates and their associated
racking have been moved and re-assembled (the racks that is) into long-term
storage at Laundry Farm (sic!). The APM itself is due to be removed in May
(MJI found out after the meeting that this was now scheduled for July
[ STH :-( PSB :-) but watch this space ]. Planning permission for the
refurbishment works, including a new roof and some new windows, is due
by the end of April. MJI noted that he didn't have any up-to-date
information about this and said that he would check progress on this
with Paul Aslin. <<<<
PDR travel plans
The PDR is scheduled for 13th May. For CASU it was decided that PSB, JRL,
MJI and STH should go over the night before and stay for at least two nights.
There would thus be no time pressure on the PDR to finish early, so that
all that needed to be discussed could be covered. It would also provide an
opportunity to socialize with ESO staff in the evening in order to establish
a good working relationship.
Continuing Actions
------------------
STH propagated new standards into the Calibration Plan (by Monday)
STH finish looking at the spatial systematics in the UFTI standards data and
