just in case anyone is interested in analysing data from these cameras, just did an inspection of a FITs sub from Nebulosity and all numbers that came up were divisible by 16 - conclusion: that the lower 4 bits are padded to give 16 bit numbers using a 12 bit ADC. So if trying to work stuff out in electrons, divide the ADU by 16 before taking the gain into account.
