Abstract We perform a K-matrix analysis of IJ PC =00++, 10++, 02++, and 12++ meson partial waves using GAMS data on π− p → π0π0 n, ηηn, ηη'n that are supplemented with BNL data on π− p → K $$\bar K$$ n and Crystal Barrel data on p $$\bar p$$ (at rest) → π0π0π0, π0ηη, π0π0η. The positions of the amplitude poles (physical resonances) are determined, together with the positions of the K-matrix poles (bare states) and the values of barestate couplings to two-meson channels. The nonet classification of the bare states found in the present analysis is discussed.
