I must have been delirious when I wrote the description - changed it even more. I'll try to troubleshoot and fix the issue tomorrow...

| 1 | | To me, it seems like binning an observable {{{O(x)}}} over {{{x}}} results in a histogram multiplied by {{{abs(x)}}}. As an example, I have attached the result of binning {{{\theta}}} (polar angle) and {{{\cos\theta}}} as functions of {{{\theta}}} for a constant 2->2 matrix element with massless phasespace (attached together with the sindarin input and the hacked matrix element). Contrary to the expectation of seeing distributions like {{{\sin\theta}}} resp. {{{1}}}, the result looks like {{{\abs\theta*\sin\theta}}} resp. {{{\abs\theta}}}. I've attached the faulty histograms together with the WHIZARD 1.95 result (which looks correct to me). |
