- [x] 1. Move it to `proto_nd_flow` - [ ] 2. Configure the readout window/ drift window to be v_drift (e_field) dependent - [ ] 3. If it is a beam event, set the t0 to the middle of the beam window 4. ~~Remove `nhit_cut` for external trigger~~ (I think set up `nhit_cut` to 1 is clean enough to achieve the goal.)
