LAFTER application to experimental maps recovers regions of low local resolution at low contours. LAFTER filtered volumes for EMD-3048 (A) and EMD-6721 (B) respectively. In each case the density is shown as a surface representation, with the corresponding deposited density and a region of higher resolution density shown for the purposes of comparison. The experimental densities are highly disrupted given their low local resolution and required filtering or further processing to interpret in each case. Curves for the half-set FSC, C_ref and Filter-Sum xFSC are adjacent as described in the key.
