Abstract:
    We present broadband photometry and provide a quantitative analysis of
    the structure of galaxies in the inner region of the Abell Cluster
    2443 (z~0.1). The galaxy parameters have been derived by fitting a
    two-component model (Sersic r^1/n^ bulge and exponential disk) to a
    magnitude-limited sample. Using a new method of analysis that takes
    into account the effects of seeing on the structural parameters and
    considers ellipticity as an active parameter, we avoid systematic
    errors arising from assumptions of circular symmetry. Of the sample
    galaxies, 76% were classified with these models, while the rest were
    morphologically peculiar. For the spiral galaxies, the relation
    between n and B/D is consistent with the trend observed in nearby
    field galaxy samples. The Sersic index n (which can be considered as a
    concentration index) of the elliptical galaxies is correlated with the
    local surface density of the cluster. Monte Carlo simulations were
    used to check the reliability of the method and determine the
    magnitude selection criteria.
    Observations were obtained on 1998 August 19 at the 2.5 m Nordic
    Optical Telescope (NOT) at the Observatorio del Roque de los Muchachos
    on La Palma. The prime-focus CCD camera was used with pixel scale of
    0.11"/pix, and the seeing ranged from FWHM 0.88" to 1".
