A neutral hydrogen survey of polar ring galaxies - III. Nancay observations and comparison with published data

A total of 50 optically selected polar ring galaxies, polar ring galaxy can didates and related objects were observed in the 21-cm H I line with the Na ncay decimetric radio telescope and 31 were detected. The objects, selected by their optical morphology, are all north of declination -39 degrees, and generally relatively nearby (V< 8900 km s(-1)) and/or bright (m(B) < 15.5) . The H I line data are presented for all 74 galaxies observed for the surv ey with the Effelsberg, Green Bank or Nancay radio telescopes, as well as a ll other published H I line parameters of these objects. Three objects were observed and detected by us at Parkes. A total of 59 objects were detected . For each object a brief description is given based on a literature search .
