Current sheet crossings at different heliocentric distances (left column 0.75 AU, right column 0.54 AU). Panel a: magnetic field in SRF coordinates. Panel b: E_y (black) and −(v_HT × B)_y with v_HT from PAS (blue) and RPW (red). Panel c: plasma density from PAS. Panels d–f: same format as a-c for a different current sheet where PAS data are unavailable. Plasma density was estimated from the spacecraft potential (Khotyaintsev et al. 2021).
