oops, the messaage has run away ... :-)

so, I use Source_Maxwell source to generate neutrons, and detect
them with 1D detector. And, I couldn't understand the imeaning of `N'
colon from the detector out file. `I' shows the actual distribution -
that's what I want. I believe that detector catches less neutrons for
one bin and more for another bin, in accordance for the maxwell
distribution.  But I found in the manual:

  One-dimentional histogran detectors: ...
      Each line contains a number identifying the bin followed by three
      numbers: the simulated intensity, an estimate of the SE, and the
      number of neutron events for this bin.

And the last, "number of neutron events for the bin", is _constant_ for
the maxwell source distribution (I guess for any other distribution

Could anybody explain me what the `N' colon means? At first time
I pointed that this colon looked like transmission function for
netron guides. But then I calculated I(after_guide)/I(before_guide)
and found result _quantatively_ different from N(after_guide).

Thank you!
