  We present a statistically motivated method to extract magnonic contrast from
STXM-FMR measurement with microwave frequencies of the order of \unit[10]{GHz}.
With this method it is possible to generate phase and amplitude profiles with a
spatial resolution of about \unit[30]{nm} given by the STXM resolution,
furthermore this method allows fo a rigoros transformation to reciprocal
\vec{k}-space, revealing \vec{k}-dependent magnon properties.
