| Abstract | New high signal-to-noise ratio 21 cm H i line profiles have been obtained for 104 galaxies with the Green Bank 43 m telescope. The primary sample is composed of isolated spirals with no known optical companions within a 1 deg radius and a median ratio of optical diameter to beamwidth of 0.17. An effort was made to ensure linearity of baseline fitting and precise flux density calibration to better than 5%. Two quantit ... |
