Plot globalCosmicMuons tracks, and angles between tracks for events with two tracks.
Plot relative pT error, dxy and dz w.r.t. primary vertex; require trigger; make sets of plots with different parameters; run over mfv_signal_samples.
Plot vy vs. vx of cosmic tracks; pt, eta, phi, dxy, dz of generated muons; for each cosmic track, scatter plot fraction of hits shared with a general track vs. number of general tracks sharing that fraction.
