custom model to fit a 2D moffat model to data, equate that to F_OIII_xy, then pass it to a 1D custom Gaussian equation to get a model spectrum. The idea is to have x, y and l (wavelength) as inputs, then the amplitude is fixed as it is calculated. When I run it I normally get mismatched dimension errors: wavelength is a 271 long list, and then x…
