WebApr 11, 2024 · A threshold of two percent was chosen, meaning the 2\% points with the lowest neighborhood density were removed. The statistics show lower mean and standard deviation in residuals to the photons, but higher mean and standard deviation in residuals to the GLO-30 DEM. Therefore the analysis was conducted on the full signal photon beam. Webγ the average energy per photon is then [average energy per photon] = 2.7 k BT. This result is similar, but not identical to what we saw in the previous lecture for ordinary particles, …
