J/AJ/114/122 J/AJ/114/122 Spectroscopy of edge-on spirals R Giovanelli E Avera I D Karachentsev Astron. J. 114 122 1997 1997AJ....114..122G VII/162 : Flat Galaxy Catalogue (Karachentsev+ 1993) Radial velocities Radio lines 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.
