Spectropolarimetry of SN 2008fp along the dominant (upper) and orthogonal (lower) axes (filled symbols) on day +6. The underlying solid curve traces the unbinned observed spectrum of SN 2008fp on the same epoch. For comparison the scaled data of SN 2006X are presented as well (empty symbols; Patat et al. 2009). The short-dashed line is a best fit to the SN 2006X data using a Serkowski law (λ_max = 3500 Å, K = 1.30), while the dotted line is the same but with K given by the Whittet et al. (1992) relation (K = 0.59). The large, filled dots indicate the scaled broad-band polarimetry measurements of SN 1986G (Hough et al. 1987). The long-dashed curve traces a best-fit Serkowski law (λ_max = 4300 Å, K = 1.10).
