Notes. Here we used a profile consisting of a King core fixed at 11.6 pc in effective radius and a variable Sérsic Envelope component. The second and third column show the magnitude of both components. The fourth column shows the effective radius of the Sérsic envelope and the fifth column the best-fit Sérsic index. The relative change in χ2 between the K+S fit and the original Sérsic-only fit is shown in the second to last column. In the last column, the expected tidal radius for these objects according to Eq. (8) are shown.
