[phenixbb] Weird occupancy values in HySS

[Pavel Afonine]

Hi Dominic,

I don't think you should interpret occupancy values at phasing stage too 
literally. The sites may be partially occupied or belong to other 
chemical species, etc. It doesn't matter as long as you get phasing 
solved. Where it does matter is later in refinement but then restraints 
or constraints will be applied to refining parameters and you will be 
getting meaningful parameter values.
