Combined PB response for our ALMA mosaics at the representative frequency of 109.0 GHz (band 3, left panel) and for the aggregate continuum mosaic image of ALMA band 6 (right panel). The white contours correspond to a PB response of 30% (solid line) and 50% (dashed line). The circles show the disposition of the pointings with diameter equal to the HPBW of the ALMA 12 m antennas at the reference frequency of the setup.
