#2753, no target field, CH2 foil in LHe. Nilanga suggested me to cut on vz to separate CH2 foil, and plot dp again to see how C and H peaks will be enhanced. In Figure 1, the first pad is the dp plot of central hole, same one in the referred entry; the second pad is the vz distribution with cut dp>-0.0003 to choose the C12 peak (mystery here: this C12 peak position is different from the C12 target run, see in referred entry). In Figure 2, they are with difference vz cuts from Figure 1. The one with abs(vz)<1.e-3 looks enhancing C12 peak. Figure 3 shows the vz with cut dp>-0.0003, but including the entire sieve holes. It has several peaks, which I don't understand here.
