Abstract:
A compilation of 21 cm line spectral parameters specifically designed
for application of the Tully-Fisher (TF) distance method is presented
for 1201 spiral galaxies, primarily field Sc galaxies, for which
optical I-band photometric imaging is also available. New H I line
spectra have been obtained for 881 galaxies. For an additional 320
galaxies, spectra available in a digital archive have been reexamined
to allow application of a single algorithm for the derivation of the
TF velocity width parameter. A velocity width algorithm is used that
provides a robust measurement of rotational velocity and permits an
estimate of the error on that width taking into account the effects of
instrumental broadening and signal-to-noise. The digital data are used
to establish regression relations between measurements of velocity
widths using other common prescriptions so that comparable widths can
be derived through conversion of values published in the literature.
The uniform H I line widths presented here provide the rotational
velocity measurement to be used in deriving peculiar velocities via
the TF method.

Note (1): 14 to 12901, UGC number; 20471 to 630257, AGC number
Note (2): MCG number were corrected from a bad format in the original version.
For AGC 530053 (MCG -33-40-14), the coordinates correspond to
MGC-03-34-014, which is not AGC 530053
For UGC 12355 (MCG +25-80-63), the coordinates do not correspond
to MCG+02-58-063
Note (3): The first code refers to the origin and configuration of the spectrum
from which parameters are derived:
(a) Arecibo spectrum, 20 MHz/512 channels
(b) Arecibo spectrum, 10 MHz/252 channels
(c) Arecibo spectrum, 10 MHz/512 channels
(d) Arecibo spectrum, 10 MHz/504 channels
(e) Arecibo spectrum, 5 MHz/512 channels
(f) Effelsberg spectrum, 25 MHz/512 channels
(g) Effelsberg spectrum, 12.5 MHz/512 channels
(h) Green Bank 91 m spectrum, 10 MHz/192 channels
(i) Green Bank 91 m spectrum, 5 MHz/192 channels
(j) Green Bank 43 m spectrum, 20 MHz/512 channels
(k) Green Bank 43 m spectrum, 10 MHz/512 channels
(l) Green Bank 43 m spectrum, 5 MHz/512 channels
(m) Nangay spectrum, 6.4 MHz/256 channels
The second code is the smoothing code:
(H) single Hanning only
(B) Hanning plus three-channel boxcar
The third is a qualitative assessment of the quality of the profile for
TF applications:
(G) good
(F) fair
(S) single peak
(P) poor quality for TF applications
(M) marginal detection
(C) confused
Velocity widths measured from profiles classified as good detections
should be useful for TF applications; those measured on profiles
denoted "F" should be used with caution. Because the width measuring
algorithm is designed for application to two-horned profiles, the
widths measured on single peaked profiles should also be used with
caution, as they may underestimate the true rotation width.
Widths in the last three categories cannot be used for TF purposes. A
designation of marginal detection is given to those cases in which
the signal has not been verified through adequate reobservation.
Confusion is identified only when contamination from another galaxy
in the beam is certain.
Another code follows where applicable that indicates inclusion in
other compilations:
"c" for the cluster compilation of Giovanelli et al. (1997,
Cat. J/AJ/113/22)
"a" for the study of asymmetry in H I profiles by Haynes et al.
(1998AJ....115...62H 1998AJ....115...62H)
