That's what I would have thought. I haven't used one of these CMOS cameras but my FLIs have 2 digitisation speeds with different read noises.
I have had it happen where I forget to reset the digitisation to the lower read noise level (and slower downloads) after using it at the higher download speed to speed up focusing. Flats then do not work well in that scenario where the flats were taken with the slower low read noise digitisation but the lights were taken with the fast download with the higher read noise.
Also is it possible to have less than 1 electron read noise? What does .16 electron mean? Several pixels of zero and one with one electron in it?
