Mimir K-band image (from Figure 2), with overlaid thin black contours showing HAWC+ 216 μm total intensity and orange polygon showing HAWC+ survey extent. Blue vectors display H-band polarization percentages and PAs for background stars having PS/N greater than 1.6. Green vectors show similar K-band values for similarly selected stars. Thicker vectors represent greater PS/N values. Magenta circles with red vector inlays identify the locations and sizes of the synthetic apertures within which significant 216 μm polarization was detected, and for which the red vectors encode percentage polarizations and B-field PAs. The aperture closest to the 216 μm intensity peak is centered on the YSO coordinates. Apertures for which significant polarization was not detected are shown as the dashed black circles. Reference percentage polarization lengths are shown in the lower right corner, color coded to the the HAWC+ E band, Mimir H band, and Mimir K band, respectively.
