keyword=Compton photon collimator moved
A new pointer was installed on the Compton photon detector table, allowing for a better alignment of the collimator. It turns out the collimator was about 3mm too low, and the collimator has been moved up 3mm, so that it is centered on the GSO at table position x=74mm and y=38.5mm (and the beam should be centered on the collimator at this position as well).
