distribution of warm pixels

Home Forums Spectroscopy New Atik 460, does it have too many hot pixels? distribution of warm pixels

Looking in detail at the distribution of these warm pixels in my camera it seems most of them fall between 500-800 ADU, causing the “knee” in the cumulative distribution described in the ARAS thread. They are in fixed positions and only represent ~1 in every 2000 pixels though and are low enough to be corrected by a dark provided they are otherwise well behaved.
