We have obtained new constraints on the cosmological parameters Ωm and σ8 from the peculiar velocities of flat edge-on spiral galaxies from the RFGC catalog. Based on these results presented graphically, we have found the quantitative condition (Ωm/0.3)0.37σ8 = 0.92 ± 0.05. The estimates of Ωm and σ8, along with their combinations Ωmασ8 for various α, are compared with the estimates by other authors.
