Mean ADU for ATIK 3l4e (Sony ICX205 CCD)

I now have 2 ATIK CCD cameras…The 383L and 3l4e, both monochrome. I have already set up my equipment profiles but have never taken flats with my smaller ATIK 3l4e. Does anyone know what I should use for the mean ADU value in the Flats Calibration Wizard? - Thanks in advance.

I use target values of around 28k for my flats with my 314e.


Many thanks David for your prompt reply.
