The nominal beam center in the field-free hole is 4 mm above the hole’s axis; the nominal beam center in the bending channel (at the septum entrance face) is 6 mm above the bottom of the channel. The upstream kicker(s) separate the kicked and non-kicked beams by 15 mm at the septum’s entrance face. Since the field-free hole is 20 mm in diameter, putting the beam 4 mm above the hole’s axis means that it is 6 mm below the top of the hole. The “blade” between the hole and bending channel is 3 mm thick.  So the beams (kicked and non-kicked) are 15 mm apart at the septum’s entrance face. The kicked beam is also pointing slightly upward w.r.t. the bending channel, but we decided to measure in the channel parallel to its floor.  The beam in x, is centered on the center of the field free axis.
