Fig. 1

All the panels are based on the rotation curve of KK 246 from Kreckel et al. (2011), corrected for beam-smearing (see text for details). Panel a): asymmetric-drift corrected (full circles) and uncorrected (open circles) rotation curves of KK 246, assuming a distance of 7.8 Mpc. Panels b) − d): MOND fits of the rotation curve with distances of 9.3 Mpc (the best-fit value, which is only weakly constrained), 7.8 Mpc (Karachentsev et al. 2006), and 6.4 Mpc (Tully et al. 2008), respectively. The best-fit stellar M/L ratios (in the H-band) are 0.22, 0.98, and 1.32, respectively. The dotted line represents the Newtonian stellar contribution to the rotation curve, the dashed line is the Newtonian gas disk contribution, and the solid line is the total MOND fit.
