ClusterWheatleyPT

java.lang.Object
- etomica.virial.ClusterWheatleyPT

All Implemented Interfaces:

ClusterAbstract, ClusterAbstractMultivalue
```
public class ClusterWheatleyPT
extends java.lang.Object
implements ClusterAbstractMultivalue
```
Cluster that uses recursion to compute temperature perturbation coefficients. This awkwardly requires fR when it wants eR and fP when it wants uP. This needs BD and some sort of criteria to determine when to use BD. It acts a lot like ClusterWheatleyExtendSW, but seems more like derivatives on paper. It's missing the binomial coefficients that ClusterWheatleySoftDerivatives uses.
