  • Note: All integration times listed are on source with the main array and assume dual polarization unless otherwise noted. Times are calculated using the online ALMA Sensitivity Calculator available at the time of publication; proposers should re-calculate integration times for themselves. They do not include estimates of overhead or calibration.
