Density profile observed in the inner regions of the 26 “Little Things” galaxies from Oh et al. (2015) (blue symbols and blue region give the mean and the root mean square (RMS) dispersion among the different objects). To reduce scatter, the observed densities and radii are normalized to the density and radius where the logarithmic derivative of the circular velocity equals 0.3 (d log v_c/d log r = 0.3), denoted as ρ_0.3 and r_0.3, respectively. Polytropes are parameter-free in this representation (solid lines with the corresponding indexes given in the inset). The dashed line gives a best-fit to the observed density using a Navarro-Frenk-White (NFW) profile (Oh et al. 2015), which does not follow the observed core.
