Context. In 2020 May-June, six solar energetic ion events were observed by the Parker Solar Probe/IS IS instrument suite at ≈0.35 AU from the Sun. From standard velocity-dispersion analysis, the apparent ion path length is ≈0.625 AU at the onset of each event. Aims. We develop a formalism for estima...
