Cumulative distribution function (CDF, black points) of the angle difference between the magnetic field orientation and the PA of the cores (a), the magnetic field and the outflows (b), and the outflows and the PA of the cores (c) in W43-MM1. The black histogram shows the CDF with 5° bin-widths. The brown bars show the errors on the CDF for each bin. Colored curves are the CDFs resulting from Monte Carlo simulations of different 3D angles projected onto the plane of the sky. The different intervals of angles considered for the synthetic populations are indicated on the bottom right of the plots.
