Cylindrical RPC map
The map shows a planar view of the 2 layers of the BaBar cylindrical
RPC. It is looking at the inner side of the "opened" cylinder. The
coloured numbers on the chambers are the chamber Ids. Chambers
connected to the same HV distribution box (AluBox) are shown in the same
colour. The numbers in parentheses are the module Id of each chamber within a
layer. The table at the bottom indicates the CAEN channel feeding each
HV distribution box.
