Jeans Newtonian and MOND modeling of the projected velocity dispersion of NGC 2768. The thick lines are for isotropic cases, and the thin lines are for fits based on β_lit. Upper panel: in the Newtonian approach, the mass-follows-light models are plotted with the thick (thin) solid blue line for M/L_B = 12.1(15.0), and the NFW models with M_∗/L_B = 8.0(9.0) are r_s = 300(400) arcsec and ρ_s = 0.0045(0.0050) M_⊙ pc^-3, which are plotted with the thick (thin) dotted magenta line. Lower panel: MOND models of the projected velocity dispersion of NGC 2768 for three interpolation functions μ(r) for both isotropic and anisotropic case (based on β_lit). The standard MOND model is presented with the thick (thin) solid blue line for M/L_B = 7.6(10.2); the simple MOND model is presented with the thick (thin) dotted red line for M/L_B = 5.6(7.8); and the toy MOND model is presented with the thick (thin) dashed red line for M/L_B = 4.4(6.0). In both panels, one effective radius is indicated by a vertical dotted line.
