AATIsolineSegment::AATIsolineSegment(const AATPoint &ap,
                                     const TaskProjection &projection)
  :AATIsoline(ap, projection)
{
  IsolineCrossingFinder icf_up(ap, ell, fixed_zero, fixed_half);
  IsolineCrossingFinder icf_down(ap, ell, -fixed_half, fixed_zero);

  t_up = icf_up.solve();
  t_down = icf_down.solve();

  if ((t_up < -fixed_half) || (t_down < -fixed_half)) {
    t_up = fixed_zero;
    t_down = fixed_zero;
    // single solution only
  }
}
