Top: pseudo-bolometric light curve of SN 2022jli (black circles) computed integrating the SN spectra in the optical region between 3800 and 9000 Å (green pentagons) and taking in account the NIR contribution (red pentagons). The NIR emission during the decline from the first maximum was estimated from optical+NIR templates of SN 2013ge as described in the text, and these estimates are shown using open pentagons. The pseudo-bolometric luminosity at +383 days was estimated directly from the griJHK_s photometry. Middle: T_bb computed from a black-body fit to the spectra of SN 2022jli. Bottom: R_bb from a black-body fit to the spectra of SN 2022jli.
