Recovery of the X-ray polarisation of Swift J1727.8−1613 after the soft-to-hard spectral transition <i>(Corrigendum)</i>

(Figure presented) In Fig. 4, the X-ray hardness value for observation 8 was plotted using a count-based ratio instead of the energy-flux-based ratio used for other points in the figure. The correction of the position of this point in Fig. 4 does not affect any other figures, results, or conclusions in the paper.
