Mosaic of the north polar region with the 17 scans taken. The continuum intensity is shown in the upper panel, the linear polarisation map is shown in the middle panel, and the circular polarisation map is shown in the bottom panel. Linear polarisation is given by and circular polarisation is given by: ∫_λ|V(λ)| dλ/∫_λI(λ) dλ. The purple contour depicts the position of a coronal hole as estimated from the SDO/AIA 193 Å intensitygram.
