ADC_Keywords: Galaxies, radio ; H I data ; Redshifts Keywords: galaxies: distances and redshifts - radio lines: galaxies Abstract: We report 21-cm H I line observations of 161 galaxies located behind the Milky Way, in the Puppis region. The observations have been carried out with the Nancay radio telescope, resulting in 101 detections. Most of the galaxies observed appear in the ESO catalogue, and present apparent diameters larger than 1.6arcmin. We show that the detection rate is strongly related to the apparent diameter; it is as high as 76 per cent for diameters larger than 1.6arcmin. Half of the non-detections result, in fact, from an insufficient velocity coverage. Global parameters of the detected galaxies are computed, after a careful discussion of the correction for Galactic absorption. Description: The 21-cm H I line observations of the 161 sample galaxies were carried out with the Nancay radio telescope from 1991 to 1993. File Summary:

Note (1): Apparent diameter corrected for Galactic absorption Note (2): Notes have the following numbers: 1 = confused profile, but no other visible galaxy in the field; the companion galaxy probably has a low surface brightness 2 = poor signal-to-noise ratio; however, the detection is quite reliable; only the recension velocity can be given with some confidence (uncertainty less than 50km/s).
