## 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):

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