$\begin{figure} \includegraphics[angle=0,width=12.7cm,clip]{4931fig1.eps} \end{figure}$ Figure 1: a) ${\it UBVRI}$ photometry of SX Cas relative to the comparison star BD + 54 $^\circ$ 0011. Note how the depth of the secondary minimum (phase 0.5) increases and the primary minimum (phase 0.0) decreases toward longer wavelengths. The magnitude scale in U and B is larger by a factor of two than that used in the other panels. b) The color indices change to bluer colors at the secondary eclipse and redder at the primary eclipse.

$\begin{figure} \includegraphics[angle=0,width=11.5cm,clip]{4931fig2.eps} \end{figure}$ Figure 2: ${\it UBVRI}$ polarimetry of SX Cas in the intervals JD 2 444 867-5301 (dots) and JD 2 445 562-6000 (crosses), expressed in terms of the normalized Stokes parameters $q=P\cos 2\theta$ and $u=P\sin 2\theta$ . Nightly mean points with standard error bars ( ${\pm } \sigma$ ) are plotted against the (36.6 day) orbital phase. Second order Fourier fitting curves are also shown with dotted and dashed lines for the two intervals, respectively. The solid line gives a fit for the combined data set.

$\begin{figure} \par\includegraphics[angle=-180,width=7.5cm,clip]{4931fig3.eps} \end{figure}$ Figure 3: Map of V-band polarizations of field stars around SX Cas. The circles centered on SX Cas have radii 0.5 $^\circ$ and 1.0 $^\circ$ . The solid line labeled SX gives the polarization of the visual companion of SX Cas (in white light), and the dashed line gives the interstellar polarization of SX Cas in the V band, derived from our scattering model fittings. North is up and east to the left. The length of the line in the lower right corner corresponds to 1% degree of polarization.
