Light curve of iPTF13bvn up to Day 306 after the explosion. Explosion time is indicated with a dotted vertical line. Early photometric data from Srivastav et al. (2014) are plotted in open squares, and the latest points in the early light curves are connected to our data points (filled squares) in the nebular phase by dashed lines. Typical photometric error bars are smaller than the plotting symbol size.
