Electron Vertex reconstruction

Here are the plots of differences between the simulated x, y, and z vertex positions and the reconstructed vertex positions for a 1cm target. Each histogram corresponds to a difference in the matching coordinate i.e. Simulated Vx - Reconstructed Vx

Histogram for Vx differences

Histogram for Vy differences

Now I will show the histograms for the difference between the simulated and the reconstructed vertex positions for the proton
