J/A+AS/141/449      Coma cluster early-type galaxies         (Mehlert+, 2000)

Spatially resolved spectroscopy of Coma cluster early-type galaxies. I. The Database. Mehlert D., Saglia R.P., Bender R., Wegner G. <Astron. Astrophys. Suppl. Ser. 141, 449 (2000)> =2000A&AS..141..449M
ADC_Keywords: Clusters, galaxy ; Spectroscopy Keywords: galaxies: elliptical and lenticular, cD - kinematics and dynamics - stellar content - abundances - formation Description: Table 1 describes the photometric properties (R-band magnitude, effective radius, surface brightness, a4, ellipticity) of all 35 Coma cluster galaxies, which are investigated spectroscopically in this work. Besides the galaxy numbers given by Godwin et al. (1983, Cat. VII/42, GMP83), we also list the NGC/IC numbers as well as Dressler's numbers given in Dressler et al. (1987ApJ...313...42D, D87). Additionally the galaxy type as well as there distance to the clusters center are given. Table 5 to Table 12 (photom.dat) give the results from surface brightness and isophotal shape analysis (local surface brightness, ellipticity, position angle and Fourier coefficients along the major axis) for 8 galaxies of the sample derived from Kron Cousins R band photometry. Table 13 to Table 47 (kinema.dat) give spatially resolved kinematic parameter (v, sigma, H3, H4) for all 35 galaxies while in Table 48 to Table 82 (indice1.dat and indice2.dat) we list the radial profiles of the measured line indices (Hbeta, Mg, Fe, NaD) of these galaxies. Table 4 contains the results from the comparison of our mean data within the circular standard aperture (see paper) with the mean values given by Joergensen (1999MNRAS.306..607J, J99). File Summary:
