Inner slope of the DM density profiles α against the inner radius for polytropic sphere and pseudo-isothermal model. The blue points correspond to the mean value of inner slope α_pol within the break radius for each dwarf galaxy. Similarly, the rhombus represents the inner slope α_obs within the radius derived from the observational data. The typical behaviour of the slope α against radius for the polytropical sphere, pseudo-isothermal, and NFW models are also presented. On the left side the profile of whole maximal radius of a specific galaxy is illustrated, while on the right side a closer view is presented.
