Statistical distribution of the inferred LOS magnetic field parameters at the west limb. Dark solid line: probability density function of different magnetic parameters for the pixels that are considered to give reliable inferred parameters (|B| > 600 G, see text). From left to right: probability density functions for the magnetic field strength (B), inclination (θ), azimuth (ϕ), and filling factor (α) in the LOS reference frame. In grey we show the same LOS magnetic field magnitudes for an LRF disc centre-like magnetic topology as would be observed at the west limb positions.
