Trending plot for the number of pixels on the detector of the acquisition camera that have 0 value.
Typically, not more than 6% of all pixels have 0 ADU in a dark exposure; they are potentially not
responding.
Note that as of 2017-03-24 not all pixels of the acquisition detector are saved. The image has a size of 1000x1000
instead of 2048x1536.
