Notes.
The dust continuum emission is measured at 254.5 GHz, and the uncertainties are ±1σ. For each parameter, the systematic uncertainties are tabulated separately in parentheses on a second line (see Sect. 5). In the heading of the table, e stands for the ellipticity, θe for the position angle (measured east of north), Rs for the scale radius, n for the Sérsic index, and μ for the amplification factor. Surface brightness units of Jy beam−1 are inherited from the surface brightness units of the data. Strong covariance between Rs and n (see, e.g., Fig. A.1) means that the 12CO(9 − 8) and 12CO(1 − 0) data are formally compatible with (larger) Rs and (smaller) n like those recovered for the other reconstructions.
