Observed surface density profile (dots and error bars) and best‐fit King model (solid line). The radial profile is in units of number of stars per square arcsecond. The dotted line indicates the adopted level of the background, and the model characteristic parameters (core radius r_c, concentration c, dimensionless central potential W₀) are marked in the figure. The lower panel shows the residuals between the observations and the fitted profile at each radial coordinate.
