Analysis of the magnetic input maps selected for the study. The left panels show the maps for February 15, 2021, and the middle panels the maps for February 22, 2021. The top row shows the original maps (both GONG-ADAPT maps in Carrington longitudes), while the bottom row shows the filtered maps used to initialize the simulations (spherical harmonics reconstruction up to ℓ_max = 30). The far-side AR location is marked with an orange box. In the right panel is a histogram analysis of the radial magnetic field distribution for original (top) and filtered maps (bottom), without (blue) and with (orange) the far-side AR.
