while this data was collected from an Apogee U8300, the data is equally representative of the KAF8300 as used in a camera from any manufacturer
The data was collected by taking 300 second exposures at temperatures ranging from +15C to -50C in 5C increments.
The offset was measured and subtracted from the average value measured in a 50 x 50 pixel selection box
The remaining raw signal in DN was converted to electrons using the measured value of the Kadc (0.5 e-/DN). The dark shot noise was computed by taking the square root of the measured average value and was plotted versus inverse Kelvins.
