Investigate Potential Major Shifts in NSB Average / Moon Clip #21

Closed STSpencer closed 3 years ago

STSpencer commented 3 years ago

Are there any conceivable circumstances under which the average NSB rate change across the camera reaches +/- 200 MHz/40 seconds? How does the NSB rate change in case a bright moon is directly 'clipped' by the camera (possibly by accident)?

I had a go at attempting this investigation by pointing directly at the moon during 0.49 FLI. NSB appears to just straight up crash if the moon is within the FOV:

As this is the only scenario left where I think such a major shift in NSB as to affect the flasher calibration could be possible, I think this issue should be closed.
