Models in which ultra-high energy cosmic-ray (UHECR) sources are transients that occur proportionally to the star-formation rate of each galaxy have recently been shown to roughly reproduce the intermediate-scale overdensities observed in the UHECR arrival directions at 𝐸 ≳ 40 EeV. In this contribution, we explore the prospects for a likelihood-based fit of such models to event-level
data from the Pierre Auger Observatory. Specifically, we evaluate the sensitivity to constrain the transient emission rate as well as the time spread and blurring induced by turbulent magnetic fields
in the local cosmic web. Considering also deflections by the Galactic magnetic field in realistic simulated scenarios, we investigate the ability to correctly identify the underlying magnetic-field model and quantify its impact on the parameter reconstruction.
