  We analyse a simple RPV extension of the MSSM, with bilinear
  R-parity violation in the soft terms and vevs, but not between the terms in
the superpotential. The model gives two massive neutrinos, and can fit all
constraints from neutrino data. We show analytically how to compute the lepton
number violating Lagrangian parameters from neutrino masses and mixing angles.
Conversely, we numerically vary the bilinear couplings as input parameters to
determine the allowed ranges that are consistent with neutrino data. We briefly
comment on the implications of our bounds for low energy LFV processes.
