J/AJ/117/2039       Sc galaxies I photometry, 21cm data      (Haynes+, 1999)

The I-band Tully-Fisher relation for Sc galaxies: 21 centimeter H I line data. Haynes M.P., Giovanelli R., Chamaraux P., Da Costa L.N., Freudling W., Salzer J.J., Wegner G. <Astron. J. 117, 2039 (1999)> =1999AJ....117.2039H (SIMBAD/NED BibCode)
ADC_Keywords: Galaxies, photometry ; H I data ; Radio lines Keywords: galaxies: spiral - techniques: spectroscopic 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. File Summary:

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)
