J/AJ/114/122 Spectroscopy of edge-on spirals (Giovanelli+ 1997)

Spectroscopy of edge-on spirals.

Abstract:
We present H I line observations of 744 edge-on spiral galaxies,
extracted from the Flat Galaxy Catalog of Karachentsev et al.
(1993AN....314...97K). Fluxes, systemic velocities and line widths are
given for 587 detected galaxies, as well as search parameters for 157
undetected systems. Widths are corrected for instrumental broadening,
smoothing, signal-to-noise and profile shape, and an estimate of the
error on the width is given. When corrected for turbulent broadening
and inclination angle of the disks, the velocity widths presented here
can provide the appropriate line width parameter needed to derive
distances via the Tully-Fisher relation.
