Photometry and kinematics of galaxy zmus_z1_119. First panel: HST image in f160w band (rest-frame I band). The concentric ellipses show the annuli where the surface brightness is computed. The green dashed ellipse shows the radius of the outermost Hα rotation velocity point. The blank region in the f814w image has been masked by our sigma-rejection algorithm (see text). Second panel: as in the first panel, but for the f814w band (rest-frame B band). Third panel: surface-brightness profiles in bands f160w (red circles) and f814w (blue triangles), normalised to the total light within the outermost ring. The thin dashed lines show exponential fits for R >  3.5 kpc, the solid thick lines show the cumulative light profile. Fourth panel: rotation curves. Points with error bars show υ_Hα as determined by TFM16. The black and the red solid (dashed) lines show our fiducial profiles for υ_circ and υ_⋆ respectively, assuming a flat (Keplerian) extrapolation for the circular velocity.
