Overview of 𝒞 and χ2 values obtained in the fits of our physical models.

Model Δ𝒞tot Δ𝒞IC χ SYN,flux 2 $ \chi^2_{\rm SYN,flux} $ (#) χ SYN,ext 2 $ \chi^2_{\rm SYN,ext} $ (#) Npar ΔAIC
Variable B-field model 0 0 152.7 (194) 60.3 (14) 16 0
Constant B-field model 374.0 264.1 246.0 (194) 76.9 (14) 15 372.0
Kennel & Coroniti 292.6 143.0 285.5 (194) 77.1 (14) 12 284.6

Notes. The Δ𝒞tot, Δ𝒞IC (cf. Eq. (6)), and ΔAIC values are given with respect to the variable B-field model model. The χ2-values are given together with the number of flux and extension points included in the fit. Npar denotes the number of free parameters of the model. See main text for a definition of the different quantities.
