Dear Stefan (& all, I suppose),

"nonfocusing" neutron CW instrument and describes a parabolic curve with
the minimum at roughly the 2-theta angle that matches the monochromator
"take-off" (really 2-theta) angle. For a Bragg-Bre
Stefan,
Not really. You should care about full width at half maximum - that should
not be negative in any case. As follows, negative W does not have much
sense. Negative U is also suspicious because it means that at higher angles
your peak width may stop increasing with the 2Theta increase, wh
