Abstract
Neutral hydrogen distributions from two spiral galaxies, NGC 4565 and NGC 891, are mapped on the basis of high-resolution observations with the NRAO's VLA in its 'B', 'C', and 'D' arrays. The paper considers the acquisition and reduction of the VLA data and discusses the kinematics of the H I in the two galaxies. Two H I companions of NGC 4565 are described. 45 refs.
