Histogram of relative orientation (HRO): shown are the calculated HRO relations between the magnetic field orientation and the density gradients in the Ser-emb 8 ALMA data, as well as in the simulated data within a region of ﹩3000\,\mathrm{au}﹩. Ser-emb 8 shows randomly distributed orientations, consistent with the weak-field simulations with ﹩{{ \mathcal M }}_{{\rm{A}},\mathrm{mean} \mbox{-} \mathrm{field}}\gt 1﹩. The shaded error regions reflect the variation in the multiple lines of sight used to calculate the HRO of each simulation.
