This file contains the experimental K+K- mass spectrum in the reaction e+ e- --> K+ K- gamma for the region of the charmonium resonances (3.0-4.5 GeV/c^2). The spectrum is obtained with the selection criteria described in Sec.III. The mass spectrum is related to the cross section of the process e+ e- --> K+ K- through Eq.(7). The detection efficiency, ISR luminosity, and background contributions can be obtained by interpolation between the values listed in Tables I and III for wider mass bins. Since the bin widths are narrow compared to the expected resolution, we also provide the mass resolution functions, obtained using MC simulation with M_KK near the J/psi and psi(2S) masses. These functions are presented as histograms of DeltaM, where Delta M is the difference between the reconstructed and true K+K- invariant masses. The histograms are obtained with the selection criteria described in Sec.III.
