Item Description

The value of the BSOL solvent-model parameter describing the average isotropic displacement parameter of disordered solvent atoms. This is one of the two parameters (the other is _refine.solvent_model_param_ksol) in Tronrud's method of modelling the contribution of bulk solvent to the scattering. The standard scale factor is modified according to the expression k0 exp(-B0 * s2)[1-KSOL * exp(-BSOL * s2)] where k0 and B0 are the scale factors for the protein. Ref: Tronrud, D. E. (1997). Methods Enzymol. 277, 243-268.
