Description
We present recent results comparing the dynamics of a sample of local galaxies in HI (THINGS) and CO (HERACLES). We will also compare different means of computing velocity fields and verify the interchangeability of HI and CO,
especially for the innermost stellar regions, where HI has a very low surface brightness.
