A combined fit is presented to data onpp annihilation in flight to final states ηπ 0 π 0 , π 0 π 0 , ηη, ηη and π − π + . The emphasis lies in improving an earlier study of ηπ 0 π 0 by fitting data at ninep momenta simultaneously and with parameters consistent with the two-body channels. There is evidence for all of the I = 0, C = +1qq states expected in this mass range. New resonances are reported with masses and widths (M, Γ) as follows: J PC = 4 −+ (2328 ± 38, Γ = 240 ± 90) MeV, 1 ++ (1971 ± 15, 240 ± 45) MeV, 0 −+ (2285 ± 20, 325 ± 30) MeV, and 0 −+ (2010 +35 −60 , 270 ± 60) MeV. Errors on the masses and widths of other resonances are also reduced substantially. All states lie close to parallel straight line trajectories of excitation number v. mass squared.
