Sets of plots below contain ADC and TAC spectra from the Roman Pot trigger counters, as they were in the sample of reconstructed elastic proton-proton scattering events (sqrt{s} = 200 GeV). Five datasets were used to prepare histograms: 0, 1, 4, 6, 9 (see numeration here).
One should take into account, that TAC spectra are sensitive to the time-space structure of colliding bunches (that's the reason why many "bumps" are presents in the distributions). Also, TAC spectra from Roman Pots were biased due to "TAC cut-off" (sharp right edge - loss of early events). Sets of points around TAC ~ 100 also results from the cut-off.
The PDF versions of the plots are listed at the bottom of the page.
