A Gaussian mixture approximation to a Sersic profile Component.
This Component approximates the Sersic (1968) profile, which is a widely-used (in astronomy) exponentially-declining radial profile with a single shape parameter. It is also functionally a generalization of the Gaussian (Sersic index n=0.5), exponential (n=1) and de Vaucouleurs (1948) (n=4) profiles.
This particular implementation closely matches the majority of the profile, but deliberately excludes the very inner and outermost regions.
