When the software converts the analog signal from a pixel from one of your 12-bit camera and converts into a 12 bit binary number. Let's say the Gain is set at unity and it reads 2000 electrons as a ADU value of 2000 or 0111 1101 0000. Now the ASICAP software converts that into a 16-bit image (.FIT file). Now since the image doesn't go dim, I'm assuming that the signal is not 2000 out of 65535 or 0000 0111 1101 0000 and what's really going on is that the software multiples the 12-bit signal by 16 in portion to the ADU signal. So, would it be accurate to say that the 2000 ADU 12-bit output is converted to 32000 ADU in a 16-bit image or 0111 1101 0000 0000. Is this correct?
Also, how would that conversion work if the 12-bit camera was binned 4x4?
