J/ApJ/659/162     CAS parameters of 199 nearby galaxies    (Taylor-Mager+, 2007)

Dependence of galaxy structure on rest-frame wavelength and galaxy type. Taylor-Mager V.A., Conselice C.J., Windhorst R.A., Jansen R.A. <Astrophys. J., 659, 162-187 (2007)> =2007ApJ...659..162T
ADC_Keywords: Galaxies, nearby ; Morphology Keywords: galaxies: evolution - galaxies: fundamental parameters - galaxies: high-redshift - galaxies: structure Abstract: We present a quantitative analysis of the morphologies for 199 nearby galaxies as parameterized with measurements of the concentration, asymmetry, and clumpiness (CAS) parameters at wavelengths from 0.15 to 0.85um. We find that these CAS parameters depend on both galaxy type and the wavelength of observation. As such, we use them to obtain a quantitative measure of the "morphological k-correction", i.e., the change in appearance of a galaxy with rest-frame wavelength. Description: As described in detail in Taylor et al. (2005, Cat. J/ApJ/630/784), we have selected for study a sample of 199 nearby galaxies that consists mostly of late-type spiral, irregular, and peculiar/merging galaxies. File Summary:

Note (1): Concentration (C) index in table3, Asymmetry (A) index in table4 and Clumpiness (S) index in table5. Note (2): Flag as follows: 1 = Galaxy does not meet the S/N requirements for accurate CAS parameter measurements in this image (S/N<75) 2 = Galaxy does not meet the resolution requirements for accurate CAS parameter measurements in this image (R>1.25kpc)
