Same as Fig. 7 but for coordinates x ~ 17′′ and y ~ 7′′ in Fig. 5, on July 5, 9:33–9:52 UT column (see white arrows pointing from left to right). These profiles belong to the spine of the filament. The magnetic field obtained from this particular fit for helium was B_He = 788 ± 11 G, γ_He = 95.0° ± 0.2°, and φ_He = 54.3° ± 1.1° and for silicon B_Si = 1058 ± 26 G, γ_Si = 99.5° ± 0.8°, and φ_Si = 32.2° ± 1.5° with a f ~ 0.8.
