I placed a photon source with trigger at various locations along the beam line and compared the resulting ToF spectrum with a Thorium target run. Each ToF spectrum was given a time offset equal to the time light takes to travel from room center to location of the trigger for that run, e.g. the ToF is given a +3.2 ns shift when the trigger/source is located at the beam dump (see image below). This was done to offset the effect of moving the trigger with the source.
