Hi,

I have carefully experimented and found this to be a true observation with CCD detection in general.

Signal to noise improves if one integrates a signal (e.g. over x seconds) versus accumulating over many short integration times (i.e. integrate over x/n seconds, n number of times and add the result).

I will appreciate if some one can help me derive why this is so (if it really is). Or else please point out if it is some artifact (e.g., readout noise increases in the later case or digitization noise?)

Thanks
