The sample, constructed from multiple surveys, extends to $z\\approx0.8$, with the majority of events at $z\\lesssim0.3$. We construct uniform multiband and bolometric light curves using Gaussian process regression, and determine key observed properties in the rest frame (e.g., peak luminosity, timescales, radiated energy). We find that SNe IIn span broad ranges in peak luminosity ($\\sim 10^{42}-10^{44}$ erg s$^{-1}$) and timescales ($\\","authors_text":"Daichi Hiramatsu, Edo Berger, Harsh Kumar, Peter K.
