Fixed error in the star simulation - were getting pixel values way bigger than 65,000. This was because of the Stot distribution used.

Last week, I used the scipy.skewnorm to vary Stot. Instead, I've made a function so I can use it to fit to the profiles of stars.

This was then used to fit the data taken from the real stars.

However, the sigma seems to be too big, not representative of what was gotten with the unskewed fit. The sigma here is actually xi, so the difference originates from there.
