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.
Line: 14 to 13
Gaps between bins due to non-integer bin values I believe.
EDIT: correction to xlabel: should be number of ADU

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:
