Mode Substraction
- We substracted the split mode image from the original image.

- The above graph is an example of a fitted star for summed rows. This appeared to be a good fit, although a slight skew appears to exist in this data, so we modified our fitting function in order to account for this, by changing the y term in the formula to a polynomial in y. (visible skew in y, not so much in x, left it for now).

- This was then performed, and a comparison can be seen below:

- From this, one can see that this seems to follow the points better, but not perfectly, and highlights the skew of the curve.

- It appears however that most stars summed columnly are not skewed as can be seen below:

- However, not all fits were so successful.
Fitting problems
- A recurring issue seen in our projections is the presence of more than 1 star in the cropped image, which obviously does not fit properly.
- This is currently a major issue for such scenarios, which must be resolved.
