    Re: ROC3, slot 23 noise: we found that there were some rare outliers
    in this ADC which caused problems in auto-ped. So we wrote a little
    algorithm to do two passes: first find avg and sigma, then do it
    again with a cut around 5 sigma of the avg. Actually the cut
    depends on sigma now. This seems to clean up the data from this
    slot considerably and the pedestals look good to me. (Vince still
    disagrees but I think he may have a detmap problem. He will sort
    this out later.)
