Density profile of NGC 2099. Azure points with error bars represent the observed stellar density profile. The black solid line indicates the best-fitting EEF (Elson et al. 1987) profile, while the corresponding uncertainty is indicated by the gray shaded area. The inferred core radius is indicated with the black solid vertical line, while the shaded region is its uncertainty. The best-fitting parameters are quoted in the bottom-left inset. The dashed line shows the best-fitting King (King 1962) profile.
