CDROM/AJ/V113/P1197 21 cm Spectra (Haynes+ 1997) ================================================================================ 21 cm H I Line Spectra of Galaxies in Nearby Clusters Martha P. Haynes, Riccardo Giovanelli, Terry Herter, Nicole P. Vogt, Wolfram Freudling, Marcio A. G. Maia, John J. Salzer, and Gary Wegner <1997, AJ, 113, 1197> =1997AJ....113.1197H ================================================================================ Abstract: A compilation of H I line fluxes, systemic velocities and linewidths is presented for 840 detected galaxies, mostly in the vicinities of 30 nearby rich clusters out to a redshift of z~.04, specifically for use in applications of the Tully-Fisher distance method. New 21 cm H I line profiles have been obtained for ~500 galaxies in 27 Abell clusters visible from Arecibo. Upper limits are also presented for 246 galaxies for which H I emission was not detected. In order to provide a homogeneous linewidth determination optimized for Tully-Fisher studies, these new data are supplemented by the reanalysis of previously published spectra obtained both at Arecibo and Green Bank that are available in a digital archive. Corrections for instrumental broadening, smoothing, signal-to-noise and profile shape are applied, and an estimate of the error on the width is given. When corrected for turbulent broadening and viewing angle, the corrected velocity widths presented here will provide the appropriate line width parameter needed to derive distances via the Tully-Fisher relation.
