Observed (thick black line) and modelled (thin red line) LSD Stokes I (top panels) and V (bottom panels) profiles of the photospheric lines of AU Mic, for subsets 2023A, 2023B, 2024A and 2024B (from left to right). The ZDI modeling of these profiles is described in Sec. 4. Rotation cycles (counting from 219, 244, 295 and 316 for 2023A, 2023B, 2024A and 2024B respectively, see Table A.1) are indicated to the right of all profiles, whereas ±1σ error bars are shown to the left of LSD Stokes V profiles.
