  We investigate signatures of anisotropy on the dynamics of time-resolved
near-threshold molecular photoemission, through simulations on a one-dimension
asymmetric model molecule. More precisely, we study the relationship between
the fundamental Wigner delays that fully characterizes the dynamics of
one-photon ionization, and the delays inferred from two-color interferometric
rabbit measurements. Our results highlights two different properties pertaining
to each of these delays. The first one is related to the inherent necessity to
fix an arbitrary electron position origin to define and compute de
Wigner-delay. The second one is the dependency of the rabbit delay on the
frequency of the probe laser. Our results show that the angular variations of
both delays converge for a specific choice of the position origin and in the
limit of a vanishing probe frequency.
