Appendix 2—table 3. Linear regression slope coefficients for radial (α, top) and angular (β, bottom) components of residual error against the time constant τ across participants.

Mean regression slope ± SEM: Radial (m/s) – vestibular: 0.62±0.06, visual: 0.28±0.03, combined: 0.29±0.03; angular (deg/s) – vestibular: 2.05±0.2, visual: 1.04±0.23, combined: 1.09±0.19.
