.
It will in fact decay anything into assuming the same matrix element.

Give a weight to a phase space point.
To be overridden by subclasses. For a given decay mode, dm, decaying parent particle and decayproducts, children, distributed according to a flat distribution in phase space, return a weight (less or equal to unity) modifying the flat distribution to the desired one. Note that the chosen phase space point may be rejected, but the chosen decay channel will not. This means that the weight returned by this function does not influence the branching ratios.
Reimplemented from ThePEG::FlatDecayer.

Used to multiply the bare weight to get something below unity.
In the Fortran pythia version it was set to 150 for unknown reasons.
