Figure 11: Energy spectra of the events in the FV before and after the TFC veto is applied. The solid and dashed blue lines show the data and estimated C rate before any veto is applied. The solid black line shows the data after the procedure, in which the C contribution (dashed) has been greatly suppressed. The next largest background, Bi, and the electron recoil spectra of the best estimate of the pep neutrino rate and of the upper limit of CNO neutrino rate are shown for reference. Rate values in the legend are quoted in counts/(day   100 ton) from [74].
