--------
Proposed correlator upgrade -- Wootten
There is a chart
from Webber comparing correlator capabilities.
Also see second generation correlator system requirements
and specifications.
--------
Polarization Widget -- Wootten
--------
After much discussion, it was decided that the polarization widget, perhaps
a quarter wave plate, will be inserted at Band 7.
--------
Scientific Benefits of a Single Antenna Design -- Wootten
--------
Al summarized
scientific reasons favoring a single antenna design. At its first meeting,
in item
(21), The Board endorsed the goal of the JAO to procure the production antennas
to a single design which has been prototyped and evaluated.
Note that it is a goal. Also, please see the ANATAC
Report.
--------
Illumination Offsets -- Holdaway
--------
See Mark's report on
illumination offsets tests and milestones. Recall that in ALMA Memo
No. 402, Mark showed that offsets in the illumination of the dishes by the
feeds would result in a phase graident in voltage patterns, a serious problem
for high dynamic range mosaicing. Mark notes that a simple correction algorithm
can remove essentially the entire effect of the voltage pattern phase gradient.
In the report, he explores how to measure the offsets and to apply corrections
to the (u,v) coordinates.
