Left panel: shear maps from two NFW halos with or without fiducial filaments. Top row: γ1 map generated by two NFW haloes only, while the middle row shows the γ1 map with the addition of a fiducial filament profile. Lowest row: γ2 map generated by two NFW haloes. it Right panel: results of the nulling procedure corresponding to the shear map on the left. In the top row, we see under both the X19 configuration (solid line) and C16’s (dashed line), the resulting signal is consistent with zero. When adding a fiducial filament profile, in the middle row, we see our X19 configuration correctly recovers the input value whereas the C16 configuration is biased on large scales. In the lower row, we verify that both configurations null the γ2 signal from two NFW haloes.
