Mollweide projection of the full-sky maps of the contributions from the shell of the Local Bubble to the RM, Q, and U signal (from left to right) as predicted for our different scenarios (rows). Maps are given in Galactic coordinates with the Galactic center at the center of the maps, Galactic longitude increases to the left and the Galactic north pole is at the top. Color scales are shared in columns. They range from -10 to 10 rad/m² for the RM maps and from –10 to 10 µK for Q and U maps.
