Provides a corrected formulation consistent with established scattering delay theory.

Clarifies the interpretation of time delays in molecular photoionization.

Abstract

In a recent article by P. Hockett \textit{et al.}, time delays arising in the context of molecular single-photon ionization are investigated from a theoretical point of view. We argue that one of the central equations derived in the paper is incorrect and present a reformulation that is consistent with the established treatment of angle-dependent scattering delays.
