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.

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).
