Abstract:
    Hα rotation curves for a sample of 10 late-type spiral galaxies.
    All rotation curves were derived using Harmonic decomposition method
    applied to Fabry-Perot velocity fields. We have used the rotation
    curves combined with pattern speeds from the Tremaine-Weinberg method,
    to study the dynamics of bars and spiral arms in late-type spiral
    galaxies.

Description:
    The deprojected Hα rotation curves for all galaxies in our
    sample. On average, the errors are approximately 20km/s and
    approximately 10km/s, inside and outside 1kpc radius respectively.
    To deproject the rotation curves, we have used the inclinations given
    in the paper.
