Fig 3. Tangential speeds of R0 marker for setup A with increasing frame rates.

Fig 3

Frame rates were: (a) 20 Hz, (b) 40 Hz, (c) 60 Hz, (d) 78 Hz. Since 78 Hz is above the required frame rate for setup A, the full speed rotation was tracked throughout the whole 10 seconds recording in (d), but others showed termination during the recordings.
