Notes. Rc is the core radius of the ISO DM halo, ρ0 is the central core density of the ISO DM halo, c is the concentration parameter of the NFW DM halo, R200 is the radius at which the average density of the NFW DM halo is 200ρcrit, and the parameters Υ⋆ and Υgas are the scaling factor from the stellar and gaseous disk were fixed in order to improve the results.
