Results of a dipole fit (see Eq. (1)) on the longitudinal magnetic field values using the three groups of lines.

B0 Bl φd χ2 r β Bpol
G G deg G

All lines –29  ±  3 80  ±  5 –0.31  ±  0.01 1.19 –2.12 –408
He lines –26  ±  4 78  ±  6 –0.32  ±  0.01 1.25 –1.99 –387
All but He –42  ±  7 93  ±  11 –0.27  ±  0.02 1.87 –2.61 –529

Notes. The first three columns indicate the parameters of the sine fit curve and the reduced χ2 value of the fit. The last three columns indicate the ratio r (see Eq. (2)), corresponding obliquity angle β, and derived strength of the dipolar magnetic field Bpol. 3σ errors are reported for each parameter.
