Adopted rotation curve (open black circles) for the inner regions (bottom panel) using the peak velocities and for the outer regions (top panel) using the moment-1. The dispersions take into account variation of V_r between different deconvolution models, the 2% variations around the minimum χ², and the standard deviation of the mean velocity in each bin. In both panels, the open square and asterisk symbols (in magenta and green in the online version) show V_r according to the ROTCUR and KINEMETRY deconvolution model, respectively. In the top panel the open triangles are for the moment-1 velocities deconvolved according to model-shape and model-mean (in red and blue colors, respectively in the online version).
