At the request of reviewers, I worked up the average B factor for some structures using CCP4 programme BAVERAGE. Here's one example:

Protein    33.1
Solvent    53.9
Ligand    32.9

I think the reviewer's question was directed at the quality of the model for the ligand, but I notice that the average B for solvent (mostly water, but also glycerol and sodium) is quite a bit higher. This was refined in REFMAC5 with anisotropic thermal factors. Does REFMAC5 place restraints on water that inflate its B values?
