Spatially resolved ionised outflows in HS 0810+2554 (top) and in SDSS J1353+1138 (bottom). Left panels: maps of the ratio between the [O III] outflow flux and the BLR flux (both from best-fit models). Coloured pixels refer to a S/N ≳ 2 (S/N ≳ 3) on the full [O III] emission line (i.e., narrow + outflow components) for HS 0810+2554 (SDSS J1353+1138). The positions of the continuum emission peak of the lensed images are marked with white ‘+’, while the dotted white lines indicate the contour levels of the BLR emission at 75%, 50%, and 25% of its peak; for SDSS J1353+1138, it is represented also the level at 90%. Right panels: normalised intensity profiles along the pseudo-slit (black dotted-dashed lines in the ratio map) and in circular annuli of increasing radius for HS 0810+2554 (top) and SDSS J1353+1138 (bottom), respectively: BLR model (red lines), [O III] outflow model (dotted blue lines) and [O III] blue wing from data (cyan lines). Blue points represent ratio values of the [O III] outflow flux over the BLR flux and they are referred to the right-hand logarithmic scale. The dashed black line in the plot of SDSS J1353+1138 corresponds to the radial distance of the centre of image B.
