Nick Sinev noticed a typo in the radii for layer 2 of the VXD for the Large detector (only). The radii should be: inner_radius2 = 4.375f outer_radius2 = 4.575f (was 4.875, 5.025). This leaves the layers all evenly spaced from r = 2.5-10 cm I seem to have lost (temporarily, I hope!) write access to our LCD web, so I can't update the web version!
