Hmmm
Just a question...
You talk about average combine and median combine....
Surely the need is to sum the subs - to lift the total signal...a higher total signal would reduce the shot SNR??
BTW in spectroscopy a spectrum with a SNR of around 10 is taken as the minimum for "useable data" (close to limiting magnitude), SNR>50 is good and SNR>100 is almost mandatory for ProAm contributions.....
