Abstract:
Cosmic Flows is an international multi-element project with the goal
to map motions of galaxies in the local Universe. Kinematic
information from observations in the radio HI line and photometry at
optical or near-infrared bands are acquired to derive the large
majority of distances that are obtained through the
luminosity-linewidth or Tully-Fisher relation. This paper gathers
additional observational radio data, frequently unpublished, retrieved
from the archives of Green Bank, Parkes and Arecibo telescopes.
Extracted HI profiles are consistently processed to produce linewidth
measurements. Our current 'All-Digital HI Catalog' contains a total
of 20343 HI spectra for 17738 galaxies with 14 802 galaxies with
accurate linewidth measurement useful for Tully-Fisher galaxy
distances. This addition of 4117 new measurements represents an
augmentation of 34 percent compared to our last release.
Description:
A search for archival material since 2000 obtained with the Parkes
64-m telescope led us to review observational programmes listed in
Table 1. Programmes P364 (PI: Seibel & Danziger; 69 spectra
retrieved) and P561 (Hong et al. 2013MNRAS.432.1178H 2013MNRAS.432.1178H, Cat.
J/MNRAS/432/1178; 139 spectra retrieved) produced a total of 142
measurements of linewidths that are now reduced as in Courtois et al.
(2011MNRAS.414.2005C 2011MNRAS.414.2005C, Cat. J/MNRAS/414/2005) and included in our
catalogue.
