[mmaimcal] SMA highlights

[Al Wootten]

Fringes were observed at 230 GHz on all baselines with the array formed
with Antennas 2, 3, 5 and 7 on Mars (see Test Log Entry 2143) and other
sources. As a result  new station coordinates for Antenna 7 (Pad 11) have
been inserted into the database for baseline calculation (see Test Log
Entries 2149 and 2144). Taco has put a simple atmospheric model into the
on-line program, which accounts for the difference in pad elevation (see
Test Log Entry 2149).

The holographic measurements on Antenna 7 from OCT 6 were used to make the
first surface adjustment of that antenna. New holography shows that the
rms deviation for the whole surface improved from 51 to 29 microns
(see Test Log Entry 2155).

Optical pointing data were acquired on Antennas 2, 5 and 7 and the
parameters of the model compared with those obtained in August. The
rms deviations in the fits to the model in October were in the range of
1-2 arcseconds (see Test Log Entries 2146, 2147 and 2148).

Five abstracts were submitted from SAO for the AAS meeting in Washington in
JAN 2002. The topics covered are: First images; Sgr A* monitoring, Testing
results, Holography results, and Water vapor radiometry.
