Description:
    In this Paper I present a new two-dimensional decomposition technique,
    which models the surface photometry of a galaxy with an exponential
    light profile for both bulge and disk and, when necessary, with a
    Freeman bar. The new technique w as tested for systematic errors on
    both artificial and real data and compared with widely used
    one-dimensional decomposition techniques, where the luminosity profile
    of the galaxy is used. The comparisons indicate that a decomposition
    of the two-dimensional image of the galaxy with an exponential light
    profile for both bulge and disk yields the most reproducible and
    representative bulge and disk parameters. An extensive error analysis
    was made to determine the reliability of the model parameters. If the
    model with an exponential bulge profile is a reasonable description of
    a galaxy, the maximum errors in the derived model parameters are of
    order 20%. The uncertainties in the model parameters will increase, if
    the exponential bulge function is replaced by other often used bulge
    functions as the de Vaucouleurs law. All decomposition methods were
    applied to the optical and near-infrared data set presented by de Jong
    & van der Kruit (1994), which comprises 86 galaxies in six passbands.
