+## Event file timing
+
+Each `evaluation_events/<seq>/XXXXXX.npz` holds the events that occurred during the
+inter-frame interval ending at HO3D RGB frame `XXXXXX` (between `rgb/(XXXXXX-1).jpg` and
+`rgb/XXXXXX.jpg`, ≈ 1/30 s). Inside each `.npz`, key `data` is a structured array with
+fields `(x, y, t, p)` — event pixel coords, timestamp in seconds, polarity ±1.
