Prototype at 2100V, 50/50 Ar/CO2
The paler lines are fits to a Landau dist, the darker lines are fits to a Landau-Gaussian convolution.
Ratio of MPVs of Landau fit to integration histograms... horizontal : 30deg : 45deg is 5110 : 6620 : 7160 or 1 : 1.29 : 1.40 Ideally this should be 1 : 1.15 : 1.41

50/50 premix gas, unfiltered, label reads analysis 49.1 CO2, so this is 51/49 Ar/CO2
2100V with prototype horizontal, scintillators vertical
Estimated max drift time is 650ns
Repeating the tilted measurements just in case the scintillators moved slightly between measurements
