\caption{Parameters of the oblique pulsator model of \hr\ determined from
the variation of the \ndlin\ line profile moments. This table reports stellar inclination~$i$, angles $\delta$ and $\chi$ specifying orientation of the pulsation axis, and
amplitudes (renormalised to yield the maximum surface velocity) of different spherical harmonic 
contributions to the pulsation velocity field. \label{tbl4}}
