Explosion parameters of SN 2011kl in the context of SE-SNe following Lyman et al. (2016). Top panel: created ⁵⁶Ni mass M_Ni vs. the ejected shell mass M_ej (both M_⊙). SN 2011kl has the highest ⁵⁶Ni mass of any SN in all the samples, but its ejecta mass is not remarkable. We also plot the extremal case M_Ni = M_ej (dashed line) and M_Ni = M_ej/3 (dotted line), the case for SN 2011kl. Middle panel: M_Ni vs. the kinetic energy in the ejecta E_k (in 10⁵¹ erg). SN 2011kl is once again extreme in terms of M_Ni, but its E_k is comparable to most other GRB-SNe. Bottom panel: M_ej vs. E_k. SN 2011kl is comparable to the rest of the GRB-SN sample.
