Scientific paper

Radio interferometric maps from the BIMA Survey of Nearby Galaxies (BIMA SONG) of the CO emission (1-0) for 44 spirals (Regan et al. 2001) are used for deriving velocity fields. We discuss methods for obtaining velocity fields from the CO emission and present our results for the 15 unbarred spiral galaxies in the BIMA SONG sample. In addition, we derive rotation curves for 13 of those unbarred spirals and show their residual velocity fields. Implications are discussed. This work is partially supported by NSF AST 9981289.
