Old Business
The enhanced Agenda
from last month's meeting is available. Science IPT notes
from month before last's telecon.
- Action items from previous
Science telecons:
ALMA Week: [Wootten]Provide detailed values on solar filter to
FEND by 30 April . These
values will be adopted.
[Laing]
Develop a requirement for stitching together the BEND 2 GHz sections
for overlap. In
process; see comments at CRE22,
which lead to a further linked document on this subject by Comoretto,
Butler and others. CDR is 18-19 October
[with SE] Decide when antennas are handed over to
Commissioning (after 1st light or 1st fringes?) 6-01-04 The Plan has
this happening after first light at the OSF for Optical telescope
pointing. [See CSV
Wiki]
MILESTONES: all leaders of level 3 milestones with upcoming deadlines
to report on
status. The Milestones,
with project number, are available updated for last month.

Reference Science Plan (Hogerheijde )
- This was used to estimate science needs
for image dynamic range specifications.
-5 Imaging (Holdaway)
- The ASAC requested
a set
of simulations to help them address their Charge No. 1.
- Report of
ALMA-J imaging effort
Tak Tsutsumi
has carried out imaging simulations for ACA + ALMA mosaicing for ALMA
as the final number of antennas is
approached.
Preliminary results can be

Emerson, Chandler, Lucas, Mangum, Shepherd, Wilson, Wootten, Saito,
Morita, Kawabe
- CSV Planning
underway.

Early Science Modes
-9 Any Other Matters Arising
- See
EVLA Memo No. 84 'Solving for antenna based pointing errors' for your
interest.
- Some have asked what the
ALMA Band requirements actually are, so from the adopted system
technical requirements here is a table:
Science Corner: Sebastian Wolf writes: Our most
recent feasibility study concerning future observations of young
circumstellar disks with embedded giant planets with the Atacama Large
Millimeter Array makes the prediction of possible detections not only
of the gap created by giant planets, but also of the local hot and
dense circumplanetary environment, indicating the location of the
planet in the gap. See:

Fig. 2.— Simulation of ALMA observations of disk with an
embedded planet of 1Mjup
(left column) / 5Mjup (right column) around a 0.5M⊙ / 2.5M⊙ star
(orbital radius: 5AU).
The assumed distance is 50 pc (top row) / 100 pc (bottom row). The disk
mass amounts
to Mdisk = 1.0 × 10−2M⊙. Only structures above the 2sigma -level
are shown. The size of the
combined beam is symbolized in the lower left edge of each image. Note
the reproduced
shape of the spiral wave near the planet and the slightly shadowed
region behind the planet
in the upper images. See
Date of next phone meeting According to the schedule the next one
should be on: 2004,
