Taubenberger et al. 2013 The Astrophysical Journal Letters 775 L43.

Caption: Figure 2.

Profile of the [O i] λλ6300, 6364 line in SN 2010lp, and its reproduction—within the Gauss-fitting approach of Taubenberger et al. (2009)—as a double-peaked structure atop a broad base. The narrow components have velocity offsets of ~ ± 1900 km s ⁻¹ from the rest position, and FWHM velocities of ~1700 km s ⁻¹.
