Description

This is due to a non-zero guide side. See https://pubs.aip.org/aip/rsi/article/85/11/115103/356359/Choppers-to-optimise-the-repetition-rate (https://backend.orbit.dtu.dk/ws/portalfiles/portal/102784335/1.4900958.pdf) Fig. 3 and, e.g., Eq. (6) and (7).

In practice we might also need an option to define a cutoff, e.g., to ignore the tails below a threshold.

Research direction

Start at the tof.chopper_cascade entry point and read the linked paper, especially Fig. 3 and Eqs. (6) and (7), to understand the non-zero guide-side transition time. Clarify how open-to-closed and closed-to-open tails should be represented and whether a cutoff option is required. Done means the cascade diagrams reflect the agreed transition behavior and any cutoff is tested.
