Notice: Possible errata about galaxy names: (1) File names and identification with individual galaxies might include some confusion. If individuality of galaxies is necessary, please check the correspondence of the file names with those in the original papers cited in the paper. This is because the paper was aimed at statistical correlations among the fitted parameters for a large number of galaxies, but not at analyzing individual galaxies characteristics. (2) Presented are Gaussian smoothed rotation curves used for the statistics in the paper. For explanations and references, see the manuscript and rc_atlas_web.pdf. (3) When using these RCs, cite the original papers listed in the references of the paper.
