Elastic electron scattering profile at Z=-528 and Z=-558, the two limits of the GEm keep out zone.

Profiles generated by Neven using Katherine's Euclid file (Media:qweak_gw_5-dec-07.euclid.txt) representing the collimator design dated 8/8/07 from Paulo's Drawing "Hall -V QWEAK EXPERIMENT COLLIMATOR BUNKER SETUP UPSTREAM CLEANUP COLLIMATOR" # 67503-E-00021.

The previous profiles prior to this latest change in the collimator when overlayed on top of each other looked like:

The electron profile closest to the beam pipe center appears to be about 8 cm away from the beam pipe center now instead of about 7.5 cm.
