Galactic line-effect single WR stars (from Table 3 in Harries et al. 1998). The bottom section of each panel shows the normalized intensity spectrum, the middle sections show the polarization magnitude as a percentage, and the top sections show the polarization position angle in degrees. The polarization spectra have been binned to a constant error of 0.05%. The data for WR 16 and WR 40 are from Schulte-Ladbeck (priv. comm.), the remainder are from Harries et al. (1998).
