Notes. t_rise is the time between the last non-detection and the first peak, while t_rise, min is the time between the first detection and the first peak. L_peak is the peak luminosity and E₂₀₀ is the integrated luminosity in the first 200 days since discovery.

^(a)

Heliocentric redshift was measured by averaging the position of the narrow emission lines in our observed spectra.
