Jeans Newtonian and MOND modeling of the projected velocity dispersion of NGC 4494. The thick lines are for isotropic cases, and the thin lines are for fits based on β_lit. Upper panel: fits of the projected velocity dispersion of NGC 4494 using the Newtonian approach for the inner (“in”, solid blue lines) and outer (“out”, dashed red lines) part. In the inner part, the thick line is for M/L_B = 1.2, and the thin line is for M/L_B = 1.6. In the outer part, the thick line is for M/L_B = 3.9 and the thin line is for M/L_B = 5.0. The NFW models with M_∗/L_B = 1.5(2.2), r_s = 600(650) arcsec, and ρ_s = 0.0040(0.0035) M_⊙ pc^-3 are shown with the thick (thin) dotted magenta lines. The thick dot-dashed magenta line is for the isotropic NFW model for which M/L_B = 1.2, r_s = 550 arcsec, and ρ_s = 0.0035 M_⊙ pc^-3. Lower panel: standard MOND model is presented using M/L_B = 2.2(2.4) for the isotropic (anisotropic case based on β_lit). The simple MOND model is presented using M/L_B = 1.6(1.8) for the isotropic (anisotropic case based on β_lit), and the toy MOND model is presented using M/L_B = 1.2(1.4) for the isotropic (anisotropic case based on β_lit). In both panels, one effective radius is indicated by a vertical dotted line.
