Fig. 3


Instrumental B-band (blue triangles) and V-band (green circles) light curves of SN 2014J obtained on N3. The first four panels show the differential light curves of the SN with respect to S1–S3 and S5, respectively, followed by a panel showing the reconstructed light curves using the trend-fitting algorithm (TFA) and the differential curve S1–S2. Solid lines correspond to least-square fits to the data, while black and red squares correspond to the binned V- and B-band light curve, respectively, using a bin size of 0.005 days. The B-band curves are offset for clarity by the amount indicated in each panel. Dotted lines indicate regions of significant variability.
