Description

Noticed that MCTracks from cosmics only have 2 trajectory points. This makes them not available on the event display.
This is becuase we drop trajectory points at the G4 stage:

sbndcode/sbndcode/LArG4/larg4_services_sbnd.fcl

Line 49 in 01780fe

keepGenTrajectories: ["generator"] # list of generator labels for which we want to store

We should consider keeping all trajectory points.

We can maybe sparsify them more than the generator tracks, to save space

sbndcode/sbndcode/LArG4/larg4_services_sbnd.fcl

Line 65 in 01780fe

SparsifyMargin: 0.015 # required when SparsifyTrajectories is set to true
