Model flux (top) and polarization (bottom) spectra of the subluminous DD model 5p0z22.8 at 7 days before maximum light at three inclination angles in comparison with the data of SN 2005ke (~8 days before maximum). We assumed an aspherical density structure with an axis ratio b/a = 0.82. We show the observations (black, with error bars for the polarization). For presentation, the observed polarization data were binned to 78 Å (30 pix).
