Example of reconstructed filaments at z = 0.20 (top) and z = 1.00 (bottom); with Method A (left) and Method B (right). The colour of the points represents the error estimate in degrees. Grey points correspond to galaxies, while the background map represents the galaxy density, smoothed at 3°, for visualisation purposes. The visualisation is a gnomonic projection around the point (RA = 140°, δ = 40°) with a side size of 60°. Meridians and parallels are both represented at a step of 20 deg.
