Properties of the magnetic field of TOI-1759 obtained from our ZDI analysis of the 2020 and 2021 SPIRou data sets, using both the APERO and LE reduced data.

Quantity	APERO		Libre-Esprit

	2020	2021	2020	2021
Mean magnetic field, B_m (G)	10 ± 1	9 ± 1	17 ± 3	18 ± 4
Dipole magnetic field, B_dip (G)	−14 ± 3	−14 ± 3	−13 ± 5	−17 ± 5
Tilt of the dipole field, i_dip (deg)	23 ± 5	50 ± 5	22 ± 5	46 ± 5
Poloidal component	99 ± 5%	99 ± 5%	99 ± 5%	97 ± 5%
Axisymmetric component	78 ± 5%	46 ± 5%	75 ± 5%	54 ± 5%
χ²	0.4		0.9

Notes. We list the square root of the magnetic energy at the surface, the intensity and tilt of the dipole field, the fractional energy of the poloidal component, and the fractional energy of the axisymmetric component of the poloidal field.
