Noise vs. Signal

We’ve been mucking with some algorithms for determining the baseline noise of the CCD in the phone — it is sensitive to heat. However, it is still “detecting” pixels significantly above the threshold in a very large number of instances — e.g., 60988 events out of 62250 samples — which seems way too high. A re-analysis of all these potential events is needed to determine a better filter. Also, a real cosmic ray event would leave streaks so a line detection filter down the pipeline will need to be included.

If you have ideas, please speak up. If you have a phone I can let you load an Alpha version and collect data.
