Plot comparing the rest-frame duration of the seven gold candidates (red stars for candidates with a reasonable two-image SALT2 fit and gold stars for the remaining objects) with SLSNe-I and SLSNe-II from the ZTF Bright Transient Survey. In this plot, we assume that the catalogue-matched redshift for our candidates belongs to the host (which would be the case if we treated the candidates like potential SLSNe).
