The finer points of linearity testing
Since I've taken my ST9e ccd camera off of my scope for the first time in a long while and the weather is generally bad, I've decided to re-do the linearity test for my camera. I just want to ask a few questions:
1.) I presume that all of the light frames must be bias and dark subtracted, correct?
2.) Is a standard fluorescent light indirectly illuminating the camera stable enough to do the test?
3.) Should I average several frames at each exposure time to get better statistics?
4.) What else am I forgetting?
Thanks for sharing your accumulated wisdom.
