Abstract:
We present the SFI++ data set, a homogeneously derived catalog of
photometric and rotational properties and the Tully-Fisher distances
and peculiar velocities derived from them. We make use of digital
optical images, optical long-slit spectra, and global HI line
profiles to extract parameters of relevance to disk scaling relations,
incorporating several previously published data sets as well as a new
photometric sample of some 2000 objects. According to the completeness
of available redshift samples over the sky area, we exploit both a
modified percolation algorithm and the Voronoi-Delaunay method to
assign individual galaxies to groups as well as clusters, thereby
reducing scatter introduced by local orbital motions. We also provide
corrections to the peculiar velocities for both homogeneous and
inhomogeneous Malmquist bias, making use of the 2MASS Redshift Survey
density field to approximate large-scale structure. The final SFI++
peculiar velocity catalog contains 4861 field and cluster galaxies.
Description:
The complete photometric and spectroscopic data sample is composed of
the previously published SFI (Spiral Field I-band, Haynes, 1999, Cat.
J/AJ/117/2039), SCI (Spiral Cluster I-band, Giovanelli, 1997, Cat.
J/AJ/113/22), and SC2 (Spiral Cluster I-band 2, Dale, 1999, Cat.
J/AJ/118/1468) data sets, and the until now unpublished Spiral Field
I-band 2 (SF2) sample. The HI spectroscopy observations were made with
the 305m Arecibo telescope, the late 91m and 42m Green Bank
telescopes, the Nancay radio telescope, and the Effelsberg 100m
telescope; the optical spectroscopic observations were made with the
2.3m telescope at Siding Spring Observatory, the Hale 5m telescope at
Palomar Observatory, and the Cerro Tololo Inter-American Observatory
(CTIO) 4m telescope.

Global notes:
Note (G1): UGC number for number 1 to 12921 (Cat. VII/26),
else AGC number (Arecibo General Catalog, Cat. VIII/77)
Note (G2): For SCI/SC2 clusters, we use the same numbering scheme used
for SCI/SC2 (Giovanelli, 1997, Cat. J/AJ/113/22, and Dale, 1999,
Cat. J/AJ/118/1468). For NOG groups, we use the NOG P2 numbering
scheme, but with 30000 added to each group number, so that any group
number between 30000 and 40000 is a NOG group (Giuricin, 2000,
Cat. J/ApJ/543/178). For VDM groups (Voronoi-Delaunay Method, Marinoni
et al., 2002ApJ...580..122M 2002ApJ...580..122M), the numbering scheme begins with group
number 40001, so that any group number greater than 40000 is a VDM
group. If the galaxy does not have a group assignment, the number is
given as "0".
Note (G3): the coefficient γ gives the target galaxy extinction:
ΔM = -γ.log(a/b)
where a and b are the observed semi-major and semi-minor axes
of the galaxy.
