Cosmics from prototype data of run 31962, 50/50 Ar/CO2, 2100V, scintillators above and below prototype with paddles vertical Picked events with hits in 3 straws in same vertical column in prototype. Estimate from detector geometry that track angle < 14 degrees to vertical.

Real life results from prototype 2100V 50/50 Ar/CO2 with scintillators vertical
First max in signal amplitude
Integrated signal
Garfield, 3GeV u at 0-14degrees, gain 3.84e6 (gas gain) x 0.058 (transfer function)
First max in signal amplitude
Integrated signal
Real life results from prototype 2100V 50/50 Ar/CO2 with scintillators vertical and track angle < 5 degr to vertical
First max in signal amplitude, track angle < 5 degr to vertical
Integrated signal, track angle <5 degr to vertical
