Four left panels: comparison of the Stokes profiles observed during the WLF (red lines) and in the post-WLF phase (blue lines); the * symbols in the respective colours indicate the best fit of these profiles achieved with the inversion code. Right panel: temperature stratifications obtained by the inversion code for the flare (red) and post-WLF (blue) phase; the dashed lines show the error margin determined by the inversion code SIR.
