    keyword=H peak from NH3 run

    This is from #23517 NH3 run with D=1cm slow raster and 1x1mm fast raster.
    Figure 1 shows the slow raster pattern. We then made a 1x1mm cut on slow raster, and together with fast raster gives 2x2mm beam size. Figure 2 left plot shows the sieve pattern after beam size cut. And after cut on central hole, we can see H and N peaks separated clearly (right pad).

    Statistics estimation:
    1600 events out of 5M (15 minutes). ~500 events under H peak.
