Notes. From (a) to (h) are the best-fit (maximum a posteriori) parameters from DysmalPy modelling. Values in square brackets are fixed. The rotation velocity in (d) is the intrinsic total (baryons and DM) velocity defined in Equation (1). Inclinations in (g) are inferred from the JWST/F444W image, except for CRISTAL-10a, 20 and 23, which we infer from [C II] line flux map due to lack of NIRCam data. The gas fraction f_molgas listed in (h) is estimated using the method outlined in Appendix C for galaxies with available dust continuum measurements. The 1σ uncertainties from (a) to (f) are the distance to the shortest interval containing 68% of the marginalised posterior for each parameter (See Appendix A.2 in Price et al. 2021). The ratios in (h) and (i) represent the outermost measurable radius R_out (maximum radius on either the approaching or receding side) relative to the disk effective radius R_e, disk and the beam size in half-width-half-maximum, respectively. Best-fit values of CRISTAL-05 and 22a are presented in Posses et al. (2025) and Telikova et al. (2025), respectively.
