Detailed H I kinematics of Tully-Fisher calibrator galaxies
Abstract
We present spatially resolved H I kinematics of 32 spiral galaxies which have Cepheid or/and tip of the red giant branch distances, and define a calibrator sample for the Tully-Fisher relation. The interferometric H I data for this sample were collected from available archives and supplemented with new Giant Metrewave Radio Telescope observations. This paper describes a uniform analysis of the H I kinematics of this inhomogeneous data set. Our main result is an atlas for our calibrator sample that presents global H I profiles, integrated H I column-density maps, H I surface-density profiles and, most importantly, detailed kinematic information in the form of high-quality rotation curves derived from highly resolved, two-dimensional velocity fields and position-velocity diagrams.
