Table 3. Kalman feedback gains during head and neck rotation.

As in Table 2, some feedback gains are constant and independently of $\delta t$, while some others scale with or inversely to $\delta t$ (see Supplementary methods, ‘Feedback gains of the model of head and neck motion’ for explanations). Gains that have negligible impact on the motion estimates are indicated in normal fonts, others with profound influence are indicated in bold. The feedback gains $k_{\delta V}^{\Omega }$ and $k_{\delta P}^{\Omega }$are computed as $k_{\delta V}^{\Omega }=k_{\delta V}^{{\Omega }_{TS}}+k_{\delta V}^{{\Omega }_{HT}}$ and $k_{\delta P}^{\Omega }=k_{\delta P}^{{\Omega }_{TS}}+k_{\delta P}^{{\Omega }_{HT}}$.
