Scatter plots comparing SO/PHI-HRT and HMI vector magnetic field maps. The first column compares inversion results from seven pairs of SO/PHI-HRT 60-second and HMI 720-second datasets, while the second column does the same for 38 pairs of SO/PHI-HRT 60-second and HMI 90-second datasets. The log density of the pixels is given by the colour scale and is saturated for clarity. The averaged linear fit and y = x are given by the solid grey and dashed black lines, respectively. Panels a and b: magnetic field strength. Panels c and d: magnetic field inclination (relative to the LoS). Panels e and f: magnetic field azimuth. Pixels where |ϕ_HMI − ϕ_HRT|> 90° and |B|_HRT < 600 G are omitted and not included in the fit.
