Differential cross sections and polarised photon beam asymmetries for η, η°and η+ photoproduction on the proton, produced by the GRAAL Collaboration, are presented. The results cover wide angular and enegy ranges of 40-170degrees and 550-1496 MeV (707-1496 MeV for η) respectively, and exhibit an unprecedented level of accuracy. The results are compared with predictions of several models.
