05-04: Consider using mode instead of median for scaling flats?
I've always used the mode to scale (sky/twilight) flats since I worry about the median being biased high by stars. This is obviously more processing intensive, though, so there's a trade-off. Can be implemented with statistics.mode or scipy.stats.mode.
Good suggestions, I'll a note about using mode. One question: are you typically working with integer or float data when you use mode?
My raw data are always integer counts. I'm not sure how the statistics module (or the scipy module) deal with it if it's float. Good question.
Still a good idea and still needs to be added...hopefully soon 😬
