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 for horizontal : 30° : 45° should be 1 : 1.15 : 1.41
The 45° and 0° runs were separated by 1/2 day; the 30° data was taken one week later.

Hits closer than 1mm to the wire
The events in the noise peak in the amplitude histo do not reach the integration histo because the code ignores hits with a leading edge gradient less than 1.

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
The paler lines are fits to a Landau dist, the darker lines are fits to a Landau-Gaussian convolution.
