Comparison of the bolometric luminosity evolution of AT 2023clx, against mass fallback rate models of Law-Smith et al. (2020), of a 0.1 and 1.0 M_⊙ ZAMS stars disrupted with an impact parameter of β = 0.7 and 1.25 (b ≃ 0.8) by a 10^6.0 M_⊙ BH mass. The data are not normalised; in order to convert the mass fallback rate to luminosity and for the peaks to match, a radiative efficiency parameter of 2.2 × 10⁻³ was needed for the 0.1 M_⊙ model. However, the 1.0 M_⊙ model required an unrealistically low efficiency parameter of 1.5 × 10⁻⁴ in order to match the peak luminosity. The 0.1 M_⊙ model and the data show an identical rise as well as a shallower decline (after the NUV break).
