Stacked ΔTS as a function of the EBL scaling factor α for the four models used in the optical depth measurement: A. Domínguez et al. (2011), A. Franceschini & G. Rodighiero (2017), A. Saldana-Lopez et al. (2021), and J. D. Finke et al. (2022). Vertical dashed lines mark the best-fit α for each model.
