We measured dependence of electronic dead time on the beam current at five different average beam currents from 0.245-4.1 uA on a 1um foil. He'd like a plot showing the five data points vs. beam current with their individual uncertainties, and then the average with it's uncertainty band.

We measured dependence of the physics asymmetry on the position of the beam on the target foil from two target foils: 0.225um and 1um. For each foil we measured 7 asymmetries (one at center and six others away from center). The details are described in the systematics TN on the wiki. He'd like a plot showing the measured physics asymmetries (weighted average of IN/OUT) vs. radial distance from the center (instead of using x/y values shown in the TN), and then the average with it's uncertainty band, for the two target foils.

Recreate Michael's Paper's Plot
- Remaking of Figure 6: media:Au_targetMSteigerwald.gif. The lines are a fit ( asym = a / (1.0 + alpha . d) ). On the original figure, the lines were his calculations.
