Detailed Description

\detail Parabolic admissibility tests

      - standard adm.  : max( diam(t), diam(s) ) ≤ η₂ dist(t,s)

      - extended adm.  : κ max( diam(t)², diam(s)² ) ≤ η₂ dist(t,s)

                           ⎜ m_t - m_s     ⎥              η₁
      - direction adm. : κ ⎜─────────── - c⎥ ≤ ───────────────────────
                           ⎜|m_t - m_s|    ⎥   max( diam(t), diam(s) )

with m_t/m_s being the centers of t/s and c the direction of the plane wave.
