The corresponding author found two typographical errors. The first one was found in the sixth line of Table 1, where the notation for the central value of the stellar mass had an additional delta sign. In particular, the correct error of the log-normal prior should read as follows:

σ = 1 2 log 10 M 0 + δ M + M 0 δ M dex . $$ \begin{aligned}\sigma = \frac{1}{2}\log _{10}\frac{M_{\star 0} + \delta M_{\star +}}{M_{\star 0} - \delta M_{\star -}} \, \, \mathrm{dex}.\end{aligned} $$

The second typographical error was found in Eq. (21), where a factor of two was missing (the authors knew the correct version, which was used for the results presented, but the factor was accidentally omitted during the editing process). The correct expression should read as follows:

V / gas 2 = 2 G M / gas R / gas I ( y ) . $$ \begin{aligned}V^2_{\star /\mathrm{gas}} = \frac{2 GM_{\star /\mathrm{gas}}}{R_{\star /\mathrm{gas}}}\mathcal{I} ({ y}).\end{aligned} $$

Lastly, we note that, in Appendix A.2, one can restate the likelihood purely in terms of V c = V R 2 + V a 2 $ V_{\mathrm{c}} = \sqrt{V_{\mathrm{R}}^2 + V_a^2} $ and δVc (the circular velocity including asymmetric drift correction), rather than VR and δVR (the observed rotational velocity). While this may seem somewhat trivial, as there is a direct transformation between VR and Vc, it was found to be more convenient to apply this transformation before evaluating the likelihood to work only in terms of Vc and δVc. This is not the result of an error, but the corresponding author thought that it may be helpful to future readers who may wish to reproduce the results presented or perform similar analyses.
