Notes. Magnitudes are unfiltered or r band except for the limiting magnitude of PTF12kso. For PTF12kso there is a nondetection at JD = 2 456 169.5 by LSQ (Aug. 30), which is later than the last PTF nondetection, but the limiting magnitude is unknown. LSQ discovered it at JD = 2 456 202.7324, later than PTF. For SN 2005ci the explosion date (3522.3
) derived from the expanding photospheric method (EPM; see Jones et al. 2009) using the VI bands and the first two spectra matches that derived from the PL fit which we adopted. We notice that the explosion date of SN 2005ci occurs before the last nondetection, but the magnitude limit at this phase was not deep enough (19 mag) to detect SN 2005ci.
