Parametrisation of our best-fit TiRiFiC model for UGCA 105 (cf. panel h) of Fig. 7): surface brightness or -density (SBR/SD), rotation velocity (VROT), vertical gradient of rotation velocity (DVRO), vertical gradient of radial velocity (DVRA), inclination (INCL), position angle (PA), scale height (SCHT), onset height for vertical gradient of rotation velocity (ZDRO), onset height for vertical gradient of radial velocity (ZDRA). The vertical line in each panel is drawn at the optical radius R₂₅ = 2.9 kpc. Colours have the same meaning as in Fig. 8.
