dc.description.abstract The diameters d_r, of inner ring structures in disk galaxies are used as geometric distance indicators to derive the distances of 453 spiral and lenticular galaxies, mainly in the distance interval 4 < Δ < 63 Mpc. The diameters are weighted means from the catalogs of Kormendy, Pedreros and Madore, and the authors. The distances are calculated by means of the two- and three-parameter formulae of Paper II; the adopted mean distance moduli μ_0 (r) have mean errors from all sources of 0.6-0.7 mag for the well-observed galaxies. Multiple comparisons between the distance scales derived from d_r, and from several other indicators, including the luminosity index, the hydrogen line width in spirals, the central velocity dispersion in early-type galaxies, the brightest superassociations in spirals, Type I and Type II supernovae, and the redshift, indicate an excellent systematic agreement and confirm the linearity of the scale in the distance modulus interval 28 < μ_0 (r) < 34. The main catalog is given in Appendix A. A guide to the user appears in Appendix C. The limitations and pitfalls of the method are discussed: barred spirals (SB) are best; ordinary spirals (SA) are poorest and most subject to confusion. A detailed error analysis is given in Appendix B. en_US
