_refine.solvent_model_param_ksol

Definition:

   The value of the KSOL solvent-model parameter describing
   the ratio of the electron density in the bulk solvent to the
   electron density in the molecular solute.

   This is one of the two parameters (the other is
   _refine.solvent_model_param_bsol) 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.
