Illustration of the computation of the optical depth for the 0.70 ≤ z < 0.79 bin and photon energies between 215–464 GeV using the τ-values corresponding to the three different models. The horizontal dashed line is the average optical depth derived using the three models, while the gray band shows the uncertainty encompassing the uncertainty of all models.
