Method: Define noise stats box to include a block of pixels avoiding the non-pixel gaps in the display. Since the block contains sequestial reads of the binned pixels, the standard deviation over the block is a proxy ~proxy for noise. Record std. dev and absolute singal at 50 Hz, 100Hz, and 200Hz to measure leakage. Gradually increase temp from -120C, pausing 15min at each temp to stabilize before recording. Save 10 frames at each setting for later analysis.

Surprising to me that the noise and leakage never really seemed to take off....expected to see it increase by x2 per 7K or some such, but I guess that only around room T. Will need to look at the data to understand how I'm confusing myself.
