Multicolor LCs of PTF12os (left) and iPTF13bvn (right) along with SN 2011dh (dashed black lines). The dashed colored lines represent first-order linear fits to the LC tails to estimate the late-time decline rates of the SNe (see Sect. 6). Corrections for extinction and distance have been applied according to Sects. 3 and 4. An S-correction based on a standard Johnson U-band filter has been applied to the Swift U-band data.
