The AIJ checklist mentions in section C.4.i that the values for the CCD (gain, readout noise, dark current) need to be adjusted for binned images. Could you please explain what values I have to enter in AIJ for the following actual observation of TrES-3b using an Atik 460EX with a 14" RC scope. I have used 3x3 binning and the CCD parameters are: Gain (e-/ADU): 0.27 Readout noise (e-): 5 Dark current (e-/pixel/sec): 0.004 Do I need to multiply all three values by 3x3 = 9? Thanks --Sam
