Goodness-of-fit with maximum likelihood progress
- Curve_fit fitting used the following equation:
|
| |
- Generated 100 images.
- Ran them through the finding algorithm.

Bias Frame
- Ran the background algorithm to see if the bias frame showed the gradual heating from the instrumentation of the camera.
- It did. Below are the first and last bias frames we took.

- 1 image could not be processed by the algorithm due to the threshold.
- 99 images were analysed.
- Histogram below shows the number of stars that were not detected.
- Median of not found stars is 4 stars.
Bias and Dark Frame
- Ran the background algorithm to see if the bias and dark frames showed the gradual heating from the instrumentation of the camera.
- It did. Below are the first and last bias and dark frames we took.

- Wrote an algorithm to stack images.
- The algorithms takes in 3 star coordinates from our 'base' image.
