Star Simulation

- Stot distributed using Pareto distribution
1000_Stars.png

- Star evaluated in a box, so runs quicker
- Gaussian noise added to background in addition to Poisson noise

Fitting 2D Gaussian

- 2D Gaussian fit to both real stars and simulated stars, with separate sigma and the same sigma

Fitted_Simulated_Star.pngFitted_Real_Star.png

- Fitted to two stars for a sum of Gaussians, with the same and separate sigmas
