Ligand and Ligand+environment Q-scores for submitted models with highest ligand Q-scores. Expected_Q is the expected Q-score for well-fitted models in maps at similar resolutions, based on analysis of a subset of publicly archived maps and models⁸². Q-scores well below the expected value indicate either that the map is not as well resolved as other maps at similar resolution, e.g. due to heterogeneity, or that the model is not optimally fitted to the map.

Target Map (Reported Resolution)	Model with highest ligand Q-score	Q_ligand (ligand atoms)	Q_near (atoms ≤5Å of ligand)	LIVQ5 (ligand +atoms ≤5Å of ligand)	Expected_Q at reported map resolution
T1 β-gal (1.9Å)	EM005_2	0.809	0.849	0.845	0.846
T2 RNAP (2.5Å)	EM009_1	0.707	0.735	0.731	0.690
T3 ORF3a (2.1Å)	EM016_1	0.767	0.819	0.812	0.791
