Electron Density Map

The inverse Fourier transform of the phased structure factors, giving electron density throughout the unit cell; 2mFo-DFc maps show the model-biased density and mFo-DFc difference maps show what the model is missing or over-fitting. Interpretability depends on resolution: side-chain rotamers appear near 2 Å, individual atoms only below ~1.2 Å.
