… resolved (#1819) As presented in the tracking WG meeting ([https://indico.bnl.gov/event/27589/contributions/105659/attachments/60986/104773/tracking1_040325.pdf](https://indico.bnl.gov/event/27589/contributions/105659/attachments/60986/104773/tracking1_040325.pdf)), the updated 2D MPGD digitization leads to inefficiencies for the Barrel MPGD. This PR restores the previous digitization scheme as the default, where the hits are used in the track reconstruction with high efficiency. Once the 2D readout can demonstrate comparable results, we will switch over.
