612 -All values for the GMD are also available for the** HALL GMD **which is located in the experimental hall down stream the gas attenuator. If the attenuator is on the ratio between Hall and Tunnel signal shows the attenuation. **BUT NOTE** that the filter unit and the Aperture 4 are downstream the GMD. So if filters and aperture are used this influence is NOT measured by the GMD hall !
