Does anyone know whether there is package with Sersic profile and its derivative/Hession profile?

I have something that is not released but may be useful; see the code [here](https://github.com/cgarling/GalaxyProfiles.jl/blob/main/src/surface_densities/sersic.jl) and the documentation [here](https://cgarling.github.io/GalaxyProfiles.jl/dev/). The code is kind of rough looking at it now but the math should be correct; see also [Graham & Driver 2005](https://ui.adsabs.harvard.edu/abs/2005PASA...22..118G/abstract).
