keyword=127 deg cm parasitic measurement
As a check on the parasitic measurement / two-step backgrounds,
we try a 15 minute run of gamma + d with the 4-cm cell. The histograms
below show about 1/4 of the data, cut on good reconstructions as in
earlier check. So we see mostly end-window / Al events. My naive
estimate would be for about 100 gamma + d -> p n events. We clearly
need to de-raster this.
