Map of the linear intensity in the IONIC filter (H band as described in Paper I). The range is [0–3.1 × 10⁵] erg cm^-2 s^-1 Å^-1. The snapshot corresponds to the top left snapshot at t = 21.976 year in Fig. 2. The large convective cell visible in this figure is swamped in smaller-scale photospheric structures in the Gaia G band images.
