Query: Computing period integrals of rigid double octic Calabi-Yau threefolds
  with Picard-Fuchs operator   We present a method for numerical computation of period integrals of a rigid
Calabi-Yau threefold using Picard-Fuchs operator of a one-parameter smoothing.
Our method gives a possibility of computing the lattice of period integrals of
a rigid double octic without any explicit knowledge of its geometric
properties, employing only simple facts from the theory of Fuchsian equations
and computations in MAPLE with a library for differential equations. As a
surprising consequence we also get approximations of additional integrals
related to a singular (nodal) model of considered Calabi-Yau threefold.
