Examples of two galaxies, zcos_z1_202 and zmus_z1_125, used in this work. From the left to the right: HST images in the F814W filter (roughly corresponding to I) from the CANDELS survey, total Hα intensity maps, Hα velocity fields, and the comparison between model and data through position-velocity diagrams (P-Vs) taken along the kinematic major axis. Moment maps and P-Vs are extracted from the KMOS data cubes used in this paper. For the maps: white and black crosses are the adopted centres, the grey thick line is the adopted kinematic position angle. Empty circles denote the PSFs. For the P-Vs: the x-axis represents the offset along the major axis from the galaxy centre, the y-axis the line-of-sight velocity in km s^-1 centred at the systemic velocity of the galaxy. Data are shown as blue and grey (negatives) thin lines, our best models as thick red lines. The green dots denote the ^3DBarolo’s rotation velocities.
