Notes. x (x) and y (y) helioprojected values of the central point of each FOV, the solar latitude (λ) and longitude (l) and μ = cos θ, where θ is the heliocentric angle. N is the number of repetitions of the scans of both lines at each FOV. %LIN is the percentage of the FOV that presents linear polarisation signatures above the noise level for the Fe I line. %MAG is the percentage that shows any, linear, or circular polarisation above the signal criterion for that spectral line. Target is a label to easily identify the FOV of the scan: NP for north pole, EL for east limb, and DC for disc centre.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
