ABSTRACT

Numerical calculation of normalization factor in a maximum likelihood technique providing a bin-free fit in azimuthal angles to the data is presented. It can be used for simultaneous extraction of asymmetry amplitudes with respect to the combined dependence of the cross section of hard exclusive leptoproduction of real photons on transversely polarized protons on beam charge and helicity and target transverse polarization. This method of data processing can reveal previously unseparated contributions from deeply virtual Comptonscattering and its interference with the Bethe-Heitler process.
