Magnetic field plane-of-sky orientation angle BPA vs. the log of sky-projected radial offset measured from the GF 9-2 YSO location, in arcsec, for SOFIA HAWC+ (red triangles and error bars), Mimir H (blue) and K (green), I-band (magenta; from Poidevin & Bastien 2006), and Planck 353 GHz (850 μm; orange). Symbol size and error bar thickness encode PS/N values, except for HAWC+ data, which are enlarged and thickened for emphasis. Projected offset physical distances are indicated as dashed lines connected to boxed values along the bottom axis. Central dashed black line represents a linear fit of BPA vs. offset, and the dashed gray line a power-law fit, as noted in the text, showing the nearly uniform B-field orientation from 6000 au out to more than 3 pc.
