griJH and UBV RIJH LCs and the best fits. For the three SDSS-II SNe (2007hz, 2007ih, 2007ik) from bottom to top are plotted g, r − 0.4, i − 1, J − 2.8 and H − 3.8 (no J for SN 2007ik). For the other 13 SNe are plotted U + 0.8, B, V − 0.2, R − 0.6, I − 1.6, J − 3 and H − 3.5. We note that the simultaneous gri or UBV RI fits were only used for these plots. In the analysis we use the results from the simultaneous fits of the g and r, and B and V bands only.
