No it is just a tuning.... :)


Another question is about the prior integration. Apparently the prior, RAVE

Our prior is actually classical and equivalent to a Dirichlet prior for the
RAVE value. Of course we could put the prior in other ways, put I strongly
believe that at this point the relevance of the prior is more important that
the way you use it.

Cheers,
