Meeting10/10

• Following our afternoon setting up Kstars in Ekos-INDI, we took some dark frames at ~-5 degrees C.
• Below are plots of pixel frequency vs number of photoelectrons for 5,10 and 50 seconds respectively.

• As can be seen, I believe I am currently having some issues fitting the pdf to the histogram.
• Gaps between bins due to non-integer bin values I believe.
• EDIT: correction to xlabel: should be number of ADU

Meeting18/10

• attempted to fit Gaussian with the exclusion of hot pixels by using median_filter from scipy.ndimage
• below are plots for three different exposure times of 0.1s, 10s and 300s respectively

• Also plotted mu v t and sigma v t including error bars for the full range of exposure times at -10c:
