Guys, I have the results from the dummy target thickness measurements. If anyone needs more detail see me. TARGET THICKNESS (g/cm^2) 15cm upstream 0.2546 4cm upstream 0.2540 4cm downstream 0.2532 15cm downstream 0.2535 The error on these measurements is 0.1%. This should be a conservative estimate.
