In the 3-channel analysis, we confirmed the existence of the rho(1250) meson and showed that the simultaneous existence of the rho(1450) and rho(1250) mesons does not contradict the data. The analysis indicates an importance of presence of some effective channel with the threshold at 1512 MeV, which might be interpreted as the rho sigma channel.
