The attached angular distributions appear differently after a crude plot.
Run 1860 is for through-going particles, and run 2004 is for particles
which may have stopped in the system, or just upstream of the cradle.

The broader distribution in 2004 may be evidence of muon decays.  I'd be
curious of the time distribution of the hits in the angular distribution
in run 2004.
