Quantitative morphology of E-S0 galaxies. III. Coded and parametric description of 108 galaxies in a complete sample.

MICHARD R. and MARCHAL J.

Abstract (from CDS):

A survey has been performed of the morphological and photometric properties of 108 E-S0 galaxies out of a complete sample of 112: this sample is built from the Revised Shapley-Ames Catalogue (RSA, Sandage & Tammann, 1981) keeping objects with δ>-10deg and V0<3000km/s, rejecting SB0's and Local Group dwarfs. The data were mainly derived from our CCD observations at Observatoire de Haute-Provence: the camera allowed fields of 4x7 arcmin (or 7x7 for the last run), the seeing being generally in the 2-3 arcsec FWHM range. The measurements include the isophotal analysis according to Carter's (1978), principles,and the photometric profiles along the two main axis. Opposite semi-axis are measured separately to detect asymmetries. Partial results about strongly flattened galaxies were given and discussed in Paper I and II of this series (Michard & Marchal, 1993 and 1994). The present paper gives in tabular form: - in Table 2a, 2b the most useful morphological parameters and a coded description of the 108 studied objects. This table includes a revised classification according to Hubble types, this being completed by the subclassification of ellipticals into "boxy", "disky" and "undeterminate". It also includes the classifications of envelope geometry and disk extent, as introduced in Paper I. - in Table 3a, b the usual photometric global parameters, also converted to absolute units for future reference. The tabular data is completed by individual notes for each galaxy, collected in an Appendix. A discussion of the present data will be presented in a forthcoming Paper IV : it aims at checking the working hypothesis that galaxies of both E and S0 Hubble types belong, but for a small minority, to a common population of objects with similar structures.
