0007 Collimater outer dimensions chosen to match the ZEUS design for the Luminosity monitor.
0008 Inner dimensions chosen to be 5*sigma for photon beam evaluated at far Z-end of collimator location, calculated using the max angular divergencies of the electron beam.
0009 Outer dimensions are full lengths. Inner ones are half lengths.
