  We present TVID 2, a program to numerically evaluate an important class of
planar three-loop self-energy master integrals with arbitrary masses. As with
the predecessor version (TVID 1) the integrals are separated into a known
piece, containing the UV divergencies, and a finite piece that is integrated
numerically, implemented in C. The set of master integrals under consideration
was found with self-energy diagrams containing two closed fermion loops in
mind. Two techniques are employed in deriving the expressions for the finite
pieces that are then numerically integrated: (a) Sub-loop dispersion relations
in the case of topologies containing sub-bubbles, and (b) a modification of the
procedure suggested by Ghinculov for integrals with only sub-loop triangles.
