face-to-face meeting (Christine)
Presentations are being collected at
ALMAEDM.

Reference Mission working group (someone from WG)
To be covered in normal agenda:
- Site: Memo
No. 451 'Some Error Sources for the PWV and Path Delay Estimated
from 183 GHz Radiometric Measurements at Chajnantor", by Delgado et al.
to be circulated
- Calibration: comments on new
calibration plan
comments on "science examples" document
- Configuration:
- SSR:
summary of AIPS++ review + response circulated ***DONE***
AIPS++ testing Phase II + II circulated ***DONE***
- Imaging:
Mel to look at distribution of time spent on mosaicking/single pointing
for BIMA
Mel reports: " There is a draft memo
available.
In
this memo, we characterize BIMA proposals for the period 2000--2003
into 8 categories: Science, Antenna Configuration, Help Requested,
Special Needs, Observation Type, Polarization, Receiver Band, and
Mosaicing. We present the data as tables and pie charts for each
category. Most, ~90 %, of the proposals requested (and
observed) spectral line data. Most of the proposals requested
antenna
configurations, receiver bands, and observing modes in the regime where
the BIMA telescope works best without any special requirements for
instrument or weather."

'Other
Devices'
John Richer and Richard Hills write: "Apart from a some
introductory material to set
the scene, therefore, this
note deals just with the ancillary devices
which will be used aid the primary calibration and, perhaps, the
scheduling.
We have based this on a note put together by Al Wootten which was in
turn taken largely from discussions at the meeting in Cambridge in June
2001.
Clearly there is a good deal more to be done here to determine both the
priority list and the detailed specifications. Please comment along the
lines of:
1) what important items are missing
2) what are the priorities
3) more quantitative specs
4) implementation - i.e. what can we buy and what should we make.
Unfortunately, both of us are unavailable for (the) telecon."
Extended Array
(Holdaway) Mark reports: "The specifications and
reconfiguration docs are not in good shape, but
will serve as drafts and may be useful to illustrate to the Science IPT
Meeting next week that some work is being done.
After I check the viability of the proposed antenna locations, and make
some changes, I need to do two things:
- determine if the required pad changes produce
coverage and
beams that are comparable to what we've got
right now
- if the beam and coverage decays much, determine if
the
less restricted antenna locations can be
moved a bit
to augment the decline in beam/coverage
quality.
