Finding the best radius of the aperture circle. Simulated a star with 2D Gaussian with a sigma of 2 pixels, with no background. Then, I gradually increased the radius of the circle around the star, summing the number of photoelectrons in the circle and compared to total photoelectrons in the simulated image.

100% of light, multiplier = 15.6

Fitted function. (in lab book)

- Star matching works on multiple images but still needs to be adjusted, some merging of stars between images.
- Done error propagation for HR diagram from conversion from #pes to magnitude.
