h2. Using Ceta camera in Leginon

Leginon does not handle Gain/Dark correction for Ceta camera.  It will not use Leginon-collected references even if you acquire them as it will make images worse.

Follow FEI's instruction in obtaining Gain/Dark References in the scope user interface.

Take an single exposure first in its Reference Manager Tab to make sure the intensity range is adequate.
