Notes. Field strength, magnetic field inclination, magnetic field azimuth, and the LoS magnetic field. We provide the coefficients for the SO/PHI-FDT comparison with both SDO/HMI datasets, with and without the application of the spatial SO/PHI-FDT PSF. Parameters a and b are the slope and the offset of the linear fit, including their errors. The coefficient r is the Pearson correlation coefficient for the linear fit. NOAA AR 12957/12959, 12960, and 12962 (blue, green, and yellow squares in Fig. 1). NOAA AR 12963 is not included, as explained in Sect. 4.3.
