_refine.solvent_model_param_bsol

Name:
'_refine.solvent_model_param_bsol'

Definition:

   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 * s^2^)[1-KSOL * exp(-BSOL * s^2^)]

   where k0 and B0 are the scale factors for the protein.
