Positions/GeometriesPositions/Geometries Center Lumi- and BeamCal on outgoing beam.
LumiCal: ±3.05cm BeamCal: ±3.65cm (z=370 is also used)
Angular Coverage: LumiCal: 8(13) to 28cm
26(43) to 92 mrad
BeamCal: 1.5(2) to 10(16)cm4(5) to 28(44)
Option: misplace BeamCal and keep aperture small...how to prevend dead area?
