Query: Bayesian priors and nuisance parameters   Bayesian techniques are widely used to obtain spectral functions from
correlators. We suggest a technique to rid the results of nuisance parameters,
ie, parameters which are needed for the regularization but cannot be determined
from data. We give examples where the method works, including a pion mass
extraction with two flavours of staggered quarks at a lattice spacing of about
0.07 fm. We also give an example where the method does not work.
