Results for the SEA of field components fitted by an FR model.

Model	FR frame	SEA	χ_B	100 χ_b	B₀	p
			(nT)		(nT)
L	Lepping	Mean	0.77	3.2	15.8	0.18
L	Lepping	Median	0.72	4.0	15.1	0.15
L	MV	Mean	0.80	2.8	15.5	0.20
L	MV	Median	0.80	4.8	14.9	0.19
GH	Lepping	Mean	1.20	6.2	16.8	0.15
GH	Lepping	Median	1.03	6.4	16.0	0.13
GH	MV	Mean	1.23	6.1	16.6	0.16
GH	MV	Median	1.09	7.0	16.0	0.16

Notes. The FR model corresponds to either the Lundquist (L, Eq. (A.3)) orthe Gold-Hoyle (GH, Eq. (A.4)). The FR frame is derived from the Lepping or MV method. The SEA is computed with the mean or the median of events. The fit parameters are described in Sect. 3.4.
