  Many attempts have been made to provide catalogs of potential sources of
ultra-high energy cosmic ray (UHECR) particles based on various astronomical
tracers, such as observed radio or gamma-ray emission. A closer look reveals,
however, that they all suffer from significant bias and selection effects. We
present here a demo-version of a catalog for one often-discussed UHECR source
class, radio galaxies (or radio-loud AGN), which is based on a complete
theoretical description of jet-energetics, particle acceleration physics,
relativistic beaming effects and nuclear composition, parametrized by a
comprehensible set of adjustable physical quantities. In addition to the bright
radio galaxies Centaurus A, Virgo A, Fornax A and Cygnus A discussed in
previous work, we find several sources with blazar-like properties that can
contribute on a similar level if relativistic beaming effects are considered.
We present a simple method to test the basic properties of the catalog for any
choice of parameters (without the need to run expensive simulations), and find
that in the canonical case the anisotropy signals expected from radio galaxies
promise to be in good agreement with current observational findings. In
particular, radio galaxies can reproduce almost exactly the direction of the
dipole above 8 EeV detected by the Pierre Auger Observatory if we assume that
extragalactic magnetic fields are strong (>1nG) only in structures, but very
weak in voids. We plan to provide a completed and improved version of this
catalog in electronic form, to be used in more detailed UHECR propagation
simulations. For immediate applications, we suggest a complete set of 16 strong
UHECR sources which can contribute to UHECR anisotropy on the level which can
be currently probed by experiment, and note that 6 of them have not been
considered in any previous studies.
