Maps of the Orion (top left), Taurus (top right), and Chamaeleon I (bottom) targets from C. V. Pittman et al. (2025a), with IRIS 100 μm maps (M.-A. Miville-Deschênes & G. Lagache 2005) shown in grayscale. The color bar shows the magnetospheric inclination found from the accretion flow model. Point sizes indicate d_Gaia such that more distant sources appear smaller. PAs compiled by M. Aizawa et al. (2020) are shown as colored bars. They are determined from 0° ≤ PA < 180° rather than 0° ≤ PA < 360°. The i_mag and PA values in Orion OB1b and Taurus may be spatially correlated, though the samples are too small to confirm.
