  The pasta phase in core-collapse supernova matter (finite temperatures and
fixed proton fractions) is studied within relativistic mean field models. Three
different calculations are used for comparison, the Thomas-Fermi (TF), the
Coexisting Phases (CP) and the Compressible Liquid Drop (CLD) approximations.
The effects of including light clusters in nuclear matter and the densities at
which the transitions between pasta configurations and to uniform matter occur
are also investigated. The free energy, pressure, entropy and chemical
potentials in the range of particle number densities and temperatures expected
to cover the pasta region are calculated. Finally, a comparison with a finite
temperature Skyrme-Hartree-Fock calculation is drawn.
