ALMA MEMO #428
Compact Configuration Evaluation

Keywords: Antenna Configurations, Image Simulations
In this memo, we compare the imaging performance of 3 compact
configurations. We have written MIRIAD scripts to simulate imaging
with ALMA, and pipeline the results into tables. We present a table of
beam FWHM, brightness sensitivity and sidelobe levels as a function of
declination. Single field images for source diameters 8, 16, 24, and
32 arcsec are also analyzed. Based on these results, 2 compact
arrays appear sufficient. Omitting an extended N-S compact configuration
is operationally simpler and saves about $1M.
