Southern ZOA galaxies 21cm HI-line
Listed in IVOA Registry (Virtual Observatory)
High-accuracy HI profiles and linewidths are presented for inclined ((b/a)^o^<0.5) spiral galaxies in the southern Zone of Avoidance (ZOA).
Description
These galaxies define a sample for use in the determinations of peculiar velocities using the near-infrared Tully-Fisher (TF) relation. The sample is based on the 394 HI-selected galaxies from the Parkes HI Zone of Avoidance survey (HIZOA).
Follow-up narrow-band Parkes HI observations were obtained in 2010 and 2015 for 290 galaxies, while for the further 104 galaxies, sufficiently high signal-to-noise (S/N) spectra were available from the original HIZOA data. All 394 spectra are reduced and parametrized in the same systematic way. Five different types of linewidth measurements were derived, and a Bayesian mixture model was used to derive conversion equations between these five widths.

Of the selected and measure galaxies, 342 have adequate signal to noise (S/N>=5) for use in TF distance estimation. The average value of the S/N ratio of the sample is 14.7. We present the HI parameters for these galaxies.
The sample will allow a more accurate determination of the flow field in the southern ZOA which bisects dynamically important large-scale structures such as Puppis, the Great Attractor, and the Local Void.
