Branch diagram comparing the pEW values of the Si IIλ5972 and λ6355 spectral features measured at maximum light. The diagram is populated by the Carnegie Supernova Project sample of SNe Ia (Folatelli et al. 2013; Morrell et al. 2024). Our measurements from two near-maximum light spectra of ASASSN-20jq are plotted in purple, as well as those inferred of nearly a dozen peculiar SNe Ia with commonalities with SN 2002es (see text). In addition, we plot the sample of 2003fg-like objects (Ashall et al. 2021). The Branch diagram subtypes labeled are CN: core normal, BL: broad line, CL: cool, and SS: shallow silicon.
