A few comments on setting camera data
#2
Hi Wade,

The reason we want to know the ADU values is to ensure that we don't clip the signal, and this all happens in the camera long before post processing. What happens in post processing is not important to what SkyTools does.

The true read noise does not depend on the Gain setting of the camera. It only appears to depend on it because the gain setting alters what you measure after the gain is applied. This is naturally taken into account when SkyTools does ts calculations, all of which are independent of the gain setting.
Clear skies,
Greg
