Notes. Quiescent values for host subtractions are as described in Sect. 3. The measurement uncertainties for the peak luminosity, derived purely from the uncertainty of the peak flux measurement, are of order 10−2 log10(erg s−1) in all but one case. However, the total uncertainty is dominated by the systematic uncertainty in the choice of the quiescent epoch. The time to peak is the difference between the observed brightest point and the listed zero epoch, in cases where the peak is visible. The total energy and maximum blackbody (BB) temperature are derived from BB fitting to the data, further described in Sect. 3.7. The total energy assumes a linear change in luminosity between the epochs.
