Set of 2D histograms binning the cells belonging to the protostar and circumstellar disk (see Appendix A for an overview of each object’s definition) at the final simulation snapshot of run NIMHD (t ≈ 0.55 yr after protostellar birth). These display the ambipolar (Λ_AD, blue distribution) and Ohmic (Λ_O, green distribution) Elsässer numbers as a function of radius. The gray dotted line denotes Λ = 1. The color shading is related to the average density within the bin, as indicated by the grayscale colorbar.
