Comparison of the Sérsic profile with the Spergel profile using mathematical simulations. Left: Surface density profiles for Spergel function (black) compared to the best fit with a Sérsic function (red) through mathematical simulations. Right: Comparison of the integrated surface density profiles for the Sérsic and Spergel functions shown in the left panel. The values of Re,in and Ie,in are held fixed and represent the input parameters in the Spergel profile.
