Chord distribution along a line in the local Universe
  A method is developed to compute the chord length distribution along a line
which intersects a cellular Universe. The cellular Universe is here modeled by
the Poissonian Voronoi Tessellation (PVT) and by a non-Poissonian Voronoi
Tessellation (NPVT). The distribution of the spheres is obtained from common
approximations used in modeling the volumes of Voronoi Diagrams.
  We give analytical formulas for the distributions of the lengths of chords in
both the PVT and NPVT. The astrophysical applications are made to the real Eso
Slice Project and to an artificial slice of galaxies which simulates the 2dF
Galaxy Redshift Survey.
