Cutout centred on the core of AR13470. Left column: PHI/HRT and EUI/HRI observations re-projected on the SST/CRISP frame. Right column: SST/CRISP observations for the Fe I 6173 Å continuum (wide-band filter, top), inverted LOS magnetic field (middle) and line core of Ca II 8542 Å (bottom). The white rectangles depict the sub-regions selected for the photospheric motion analyses (see text). The continuum intensities are colour-plotted on a logarithmic scale (only the values between the 0.1% ad 99.9% percentiles are mapped). The LOS magnetic field maps are shown on a linear scale ranging −500 G (black colours) to 500 G (white colours). The artificial slit traced in white colour is used later for the coronal oscillation analysis.
