Investigate sharp cut in STRs for low drift times #103

Open DJDuque opened 1 year ago

DJDuque commented 1 year ago

The currently used STR files fix the Lorentz correction to 0 for low values of drift time and it has a sharp jump. The value of the drift time at which this happens is where the Lorentz correction goes above the anode wire pitch.

The reasoning behind this was that we only care when an electron would have arrived at a different wire. Nonetheless I think that setting this correction to 0 for lower drift times introduces a bias in phi for these spacepoints.

I should just produce STR files without this cut, and just run the analysis to see if this has any effect.
