Combined 28.4 GHz polarization map at 1° resolution of the North Polar spur and the region outside its perimeter, including filament X of Vidal et al. (2015), which leaves the Galactic plane at a shallow angle from near l = 36°, and the l = 45° feature between filament X and the NPS. Colour scale is asinh, but the length scale for polarization line elements remains linear, as in all our figures.
