Abstract
Spatially filtered maps of a portion of the Galactic plane are presented in Ka band (26-36 GHz), Q band (36-46 GHz), and D band (138-150 GHz) near a declination of -60° with resolutions ranging from 0°.2 to 0°.9. The maps are optimized to detect unresolved source emission and are calibrated through observations of the planet Jupiter. Six millimeter-bright regions are detected, including the Carina Nebula and RCW 57, of which three are visible in all bands. Variability of flux density over a 3 month period has an upper limit of 3.8% for all sources seen in Ka and Q bands and 10% in D band. A fractional polarization upper limit of 0.08 is placed for all sources seen in Ka and Q bands.
