Hi, Rob. I don't have the camera with me tonight, but I have some results from yesterday with a 30s exposure at ISO 200.
[DeadPixelText] Version=1.0 Description= FileType=TIFF NumBadPixels=4 0=Hot,2820,150,77 1=Hot,1865,209,67 Ambient temperature was 20-22�C, and the camera had been turned off for a long time before the test. I'll get back to you with standardised data later.
