Table 1

Fit parameters (σ and μ) and weighting coefficients (w1 and w2) derived for the magnetic field strength distribution of data set I (sunspot group; see Figs. 1, 3).

Description Weighting coefficient Relative weighting coefficient Mean value (μ) Standard deviation (σ)
[%] [G] [G]

Log-normal distribution component I 72   000 ± 2000 66 ± 2 5.62 ± 0.03 0.80 ± 0.02
Log-normal distribution component II 37   000 ± 1500 34 ± 2 7.13 ± 0.01 0.17 ± 0.01

Notes.The reduced χ2 value (describing the goodness of the fit) has a value of 3.9.
