One of the most common usages of the radial profile script is to generate the
surface brightness radial profile. But we also need error-bars on the radial
profile, so these are the two respective MakeCatalog measurements that can be
requested from the radial profile script: '--surfacebrightness --sberror'

However, after comparing the values of '--sberror' with the scatter of surface
brightnesses of mock images (same underlying profile, only with a different
random number generator seed), we noticed that the '--sberror' column is
overestimating the errors in the central parts.

This problem was found by Raul Infante-Sainz.
