Residual plot for J16123916-1859284, shown in the same way as in Fig. 1. We highlight the residuals in the channel maps at v = 4.6, 5.5 km s⁻¹, which are those affected by cloud absorption. Moreover, in the channel map at v = 3.7 km s⁻¹, we show how csalt is able to separate the diffuse cloud emission (the localized red emission) and the Keplerian disk emission. The residual plots for all the disks analyzed in this work can be found in Appendix B and on GitHub⁴.
