We have investigated the effect of the new CLAS data consisting of the recoiled Λ polarization P , photon asymmetry Σ, target asymmetry T , and the double polarizations O x and O z , on the latest isobar models constructed for the kaon photoproduction processes γp → K + Λ and γp → K + Σ 0 . We found that those data might have significant effect, especially in the K + Λ channel, where apparent changes are observed in the predicted differential cross sections after including the new CLAS data in the fitting database. The isobar model for the K + Λ photoproduction must be accordingly modified in order to improve the agreement between model calculation and previous experimental data.
