Normalized Stokes parameters for SN 2012aw in three spectral regions devoid of strong lines covering 6000–6150 Å (circles), 6700–6900 Å (square), and 7900–8100 Å (stars) and for all seven epochs. q and u were derived by taking the mean of the binned (by 15 Å), de-redshifted data over the stated ranges; uncertainties shown are the 1-sigma spread of the data values over the same ranges. Right: Same as left, but now zooming-in on the Hα region extending ±10 000 km s−1 away from line center. In both panels, a black dot gives the average interstellar polarization inferred at 6500 Å and the dashed line indicates the dominant axis adopted for the rotation of the Stokes parameters in subsequent sections.
