Query: An extensive catalogue of early-type galaxies in the nearby Universe   We present a catalogue of 1715 early-type galaxies from the literature,
spanning the luminosity range from faint dwarf spheroidal galaxies to giant
elliptical galaxies. The aim of this catalogue is to be one of the most
comprehensive and publicly available collections of data on early-type
galaxies. The emphasis in this catalogue lies on dwarf elliptical galaxies, for
which some samples with detailed data have been published recently. For almost
all of the early-type galaxies included in it, this catalogue contains data on
their locations, distances, redshifts, half-light radii, the masses of their
stellar populations and apparent magnitudes in various passbands. Data on
metallicity and various colours are available for a majority of the galaxies
presented here. The data on magnitudes, colours, metallicities and masses of
the stellar populations is supplemented with entries that are based on fits to
data from simple stellar population models and existing data from observations.
Also, some simple transformations have been applied to the data on magnitudes,
colours and metallicities in this catalog, in order to increase the homogeneity
of this data. Estimates on the S\'{e}rsic profiles, internal velocity
dispersions, maximum rotational velocities, dynamical masses and ages are
listed for several hundreds of the galaxies in this catalogue. Finally, each
quantity listed in this catalogue is accompanied with information on its
source, so that users of this catalogue can easily exclude data that they do
not consider as reliable enough for their purposes.
