<p style="margin-top:0;margin-bottom:0">Evgeny Isupov repeated selection of gvp p--->pi^0p'---> gamma gamma p' events from the same data set and with the same selection criteria as FX did. His results for 2gamm inv masses are consistent with FX.</p>

<br>
I used FX’s cuts and plotted 2 gamma invariant mass.<br>
On the right you can see the same plot only in log scale,<br>
we can clearly see the eta meson signal.<br>
