Reproduction of the ALMA line spectrum as presented by Greaves et al. (2020), with the original and the reproduction in the left- and right-hand panels, respectively. This is after a 12th-order polynomial is removed from the spectral baseline. The reproduced spectrum is artificially scaled down by a factor of 12.8/16.1 to account for the different continuum brightnesses used in the studies. In the reproduction, the line feature shows a small velocity offset and the spectral baseline is somewhat noisy, but the overall S/N of the two features is similar.
