Fig. 4: Influence of the anisotropic molecular potential on attosecond time delays.

Difference of attosecond time delays between the emission directions A (θ = 15∘) and C (θ = 165∘) (a) and B (θ = 68∘) and C (b) for the experiment (red squares) and extracted from the simulations (black circles). The RABBITT spectra were previously averaged over the intervals of emission angles θA, θB, and θC for the emission directions A, B, and C, respectively. The blue triangles correspond to the differences of the stereo-Wigner time delays between the directions A and C (a) and B and C (b) and averaged over the corresponding emission angle intervals, respectively. The error bars were derived by error propagation from those of the single directions.
