Hi Lu,

These are respectively a parameter refined in crystallographic structures
and a quality measure of such structures.

The B factor (or ADP -> Atomic Displacement Parameters) give you an idea of
the thermal motion of the atoms.

The R factor is a measure of the agreement between the experimental data and
the refined model.

I hope this helps.

Braves gens, braves gens,
Je pousse en liberté
Dans les jardins mal fréquentés!
