Notes. Continuum levels were determined through a zeroth-order fit to line-free channels in the uv-plane for Q-band, and in the image plane for the ALMA continuum. Source sizes (diameters) are FWHM two-dimensional Gaussian fits given in (mas) = milli arcseconds = . Given flux errors are RMS errors only. Flux calibration accuracy is 5–10% for band 3 and Q-band, and 20% for band 6. For band 7 the accuracy is only a factor of two. TB is the Rayleigh-Jeans temperature over the 2D Gaussian source size. For a distance D of 59 Mpc, a size scale of 10 pc corresponds to .

(a)

Lower side band (LSB) of the band 6 observations.

(b)

Upper side band (USB) of the band 6 observations. Errors are higher than for the LSB due to more line contamination.
