First panel: comparison of synthesized BVRI SNIFS light curves of SN 2011fe, using BM12 passbands and zero points, with published photometry from Richmond & Smith (2012, RS12), Vinkó et al. (2012, V12) and Munari et al. (2013, M13). Second panel: residuals between all light curves and the SNIFS interpolated light curve, whose uncertainty is represented as the gray shaded region. Third & forth panel: median and normalized median absolute deviation of the residuals for each combination of reference (row) and comparison (column) light curves. The statistics of the residuals shown in the second panel, with SNIFS as reference, are on the topmost row of each matrix. The R_CI_C filters used by M13 are not directly comparable to RI from RS12 and V12.
