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.
