Query: No guaranteed neutrino astronomy without (enough) double bang tau and
  downward HESE muon tracks: An update version   IceCube Neutrino Astronomy is considered. The tau neutrino flavor paucity and
the asymmetry for the tracks suggest a dominant atmospheric charm noise. The
correlated cascades and tracks asymmetry with relevant statistics enforce the
charm noise dominance in the data. The charm signal may explain at once the
absence of correlation for the tracks data with the galactic plane and with
known brightest gamma sources.
