Extended Data Fig. 1: Likelihood \( {\mathcal L} \) for the coherent magnetic field to have mean (B0) and spread (σ0) values.
From: An early transition to magnetic supercriticality in star formation

a, Contours of \( {\mathcal L} \) as functions of B0 and σ0 plotted at 10%, 30%, 50%, 70% and 90% of the peak value. b, The probability distribution of B0 while allowing all possible values of σ0. c, The probability distribution of σ0 while allowing all possible values of B0.
