Spin wave
Dynamical structure factor
The sample kernel is defined by the dispersion
$$
E(h,k,l) = 2.563 \sqrt{1\gamma_{Q_{//}} ^2}
$$
and dynamic structure factor
$$
S(h,k,l) = \frac{1  \gamma_{Q_{//}} } {2 \sqrt{ 1 \gamma^2_{Q_{//}} }}
$$
where
$\gamma_{Q_{//}} = cos(h\pi) cos(k\pi)$.

I(h,E)
The MCViNE simulation accurately capture the asymmetry of the
resolution function along two lines originating from (010):

Simulated

It is also clear from this I(h) cut:
Black: simulation. Red: experimental. A constant back ground was
added to the simulated cut data.
