Peak luminosity vs. peak time measured in the rest frame for the 14 late-time flares with measured redshift (blue squares) compared with the early-time flare sample (red stars). The best fit for the whole sample accounting for the extrinsic scatter is Log [L_pk]  = (53.2 ± 0.3) + (−1.8 ± 0.1)   Log [t_pk]  with σ_ext = (0.72 ± 0.07) (pink line). The best fit for early-time flares accounting for the extrinsic scatter Log [L_pk]  = (54.8 ± 4.0) + (−2.7 ± 0.5)   Log [t_pk]  with σ_ext = (0.73 ± 0.08) (green line) is shown for comparison. The thinner lines indicate the 2σ regions for the two best-fit relations.
