VizieR Online Data Catalog: Cosmicflows-4: Tully-Fisher distances (Kourkchi+, 2020)

We accept the HI line widths and fluxes from four resources: (1) Our primary source (78% of cases) is the All Digital HI catalog (ADHI), which has been collected over the course of the Cosmicflows program (Courtois+ 2009, J/AJ/138/1938 ; 2011, J/MNRAS/414/2005 ; A. Dupuy et al. 2020, in preparation) and is accessible online at the Extragalactic Distance Database (EDD) website. (2) Most of the remainder (19% of cases) are given by the Arecibo Legacy Fast ALFA Survey (ALFALFA; Haynes+ 2011, J/AJ/142/170 ; 2018, J/ApJ/861/49) with coverage over the decl. range 0<δ<+38°. (3) In a small number of cases (50 galaxies, i.e., 0.5% of the total cases), line widths are uniquely provided by the Springob/Cornell HI catalog (Springob+ 2005, VIII/77). (4) For 3%, the source is the Pre Digital HI catalog that is available in EDD, which provides information from early analog HI line profiles, either from single beam or interferometric observations (Fisher & Tully 1981ApJS...47..139F ; Huchtmeier & Richter 1989, VIII/68).

We convert the HI flux within the 21cm line profiles, F_HI, given in the units Jy.km/s, to an HI magnitude, m₂₁, using m₂₁=-2.5logF_HI+17.40.

For the optical photometry of our galaxies, we use the SDSS DR12 data release (see Cat. V/147). For each galaxy with available SDSS data, we download all the single exposure cutouts at u, g, r, i, and z bands. For the infrared part, we obtain the W1 (3.4um) and W2 (4.6um) images of the WISE survey (see II/311), from the NASA/IPAC infrared science archive (IRSA). All of our optical and infrared images are calibrated to produce magnitudes in the AB system.
