Magnetic field strength distribution obtained for data set II (active Sun; pores). The fit was created by using two log-normal components. The first component assigned to MBPs yielded a geometric mean value of (1260  ·| ÷   1.25) G, while the second component is used for the background, which is rather weak. The reduced χ² for the fit is 3.0. For this analysis, 2624 MBP features were taken into account and occupied a fraction of the FOV of about 6%.
