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.

simulation events in the J/psi and psi(2S) mass regions).
