Sensor Analysis
A very quick question: should sensor analysis be done at a room temperature or at the same temp as the light frames (e.g. -15'C). Thanks.

Re: Sensor Analysis
Hi,
it doesn't really matter - the information that the sensor analysis extracts (e/ADU, read noise, black level values) is largely unaffected by temperature.
When using the Smart Histogram to measure sky brightness, you should do that at your imaging temperature (ie -15) as the thermal noise counts as part of the background level.
