[ccp4bb]: Defaults in RANTAN

I'm interested in using RANTAN to solve a selenium substructure. It's not
a straightforward problem, so I want to fiddle with the weighting of the
three figures of merit, which is used to select the correct solution.
It's the middle one I'm curious about, Psi-zero, which apparently uses
triplets which contain a small E-value. Do these mean anything when
working with Bijoet differences for an anomalous substructure? So should
I downweight Psi-zero's contribution to the overall FOM? The default is
0.4, but it seemed that I should set it a lot lower.
Thanks for any advice
