Gallery showing the multi-wavelength properties of the Best Disks. The first column displays the colour-composite images from HST, and if available, NIRCam/JWST images are shown in the second column. The third to fifth columns are ALMA images of [C II] emission, shown as line intensity, velocity, and velocity dispersion maps. The velocity and velocity dispersion maps are obtained by pixel-by-pixel single Gaussian fitting to the natural-weighted line cube, binned at ΔV = 20 km s⁻¹ spectral resolution. They are not corrected for spectral broadening, beam-smearing and projection. The last column shows the spectro-astrometry (SA) measurement overlaid on HST (or NIRCam/JWST if available) colour images, in which the sizes and transparencies of the points are proportional to the positional uncertainties derived using Equation 1 in Condon et al. (1998). For all panels, the contours correspond to the intensities of the [C II] line map, plotted from 1.5σ to 3σ.
