\caption{Polarimetric data for $\xi\,$Per, measured
in the $B$-band (with the addition of a 10\% neutral density
filter) during the 1989 Oct campaign are listed
according to HJD (Column 1). Columns 2 and 3 give the normalised
Stokes parameters, $q,u$, while columns 4 and 6 give the degree of
polarization, $p(B)$ and the vibration direction, $\theta$ relative
to the standard equatorial frame. Columns 5 and 7 give estimates
for the uncertainty of the $p(B)$ and $\theta$ based on the photon
count associated with the individual measurement set.}
