[Brahms-dev-l] 90 deg specturm challenge.

In view of Steve's posting and of discussion with Hongyan last week I should clarify how the dn/dy of the input
is normalized.
a) The dn/dy ~ (1-y/5.4)
b) It is normalized to 1 (one) at a rapidity value corresponding to the center of the thrown bin, or to be precise
the integral from ymin(trhoen) to ymax(thrown) is one. For non 90 deg settings it means the dn/dy = 1 at 0.83 for the
the 45 deg setting.

This seems to take care of SJS low pt part but certainly not the spike at higher pt (2 GeV) . which looks peculiar.
