Sampling in window 1 is a little odd - the distribution is incredibly narrow, if
you can even call it a distribution at all. Make sure everything is OK in that
window. In the absence of a well-defined minimum, you're not going to get a
sensible profile. People's mileage varies as far as recapitulating that PMF
curve, but I have received confirmation from at least two other people that the
PMF can be reproduced following the method in the paper.
