The results of linear regresion of differential cross sections, Σ- and T-asymmetries of η-photoproduction on protons in energy region from threshold up to 1 GeV are presented. Serious contradictions between angular distributions measured in different laboratories are revealed. The energy dependance of regression coefficients may be due to transition from energy region of S11(1535) and D13(1520) to energy region of D15(1675) and F15(1680) resonances.
