BVgri (pseudo)bolometric LCs of SN 2021aatd calculated with the SuperBol code. The orange and red filled circles denote respectively the “pure” pseudo-bolometric LC (i.e., the integration of BVgri fluxes) and the LC corrected after the integration of a blackbody (BB) function fitting of the available photometry. The black circles show the final bolometric LC of SN 2021aatd calculated from a suppressed BB estimation (see details in the text). Bolometric LCs of SNe 1987A and 2020faa (adopted from Nagy & Vinkó 2016 and Salmaso et al. 2023, respectively) are also shown.
