Analysis of Observation 1

Observation 1 image is saturated.

SaturatedImage.png

Other profile taken of same star with less saturation, fwhm calculated.

BrightestSortOfSaturated.png

Different star in same image used, it's less bright, but not saturated.

Then, I used took a profile of a star in the simulated star field

Star Field Simulation

Star field simulation now has some random shape - not based on real data.
Poisson noise added to star contributions
Stot is now normally distributed rather than uniformly
