Detailed Description

template<typename InterpolationTargetTag, typename Frame>
struct intrp::TargetPoints::ApparentHorizon< InterpolationTargetTag, Frame >

Computes points on a trial apparent horizon`.

This differs from KerrHorizon in the following ways:

  • It supplies points on a prolonged Strahlkorper, at a higher resolution than the Strahlkorper in the DataBox, as needed for horizon finding.
  • It uses a FastFlow in the DataBox.
  • It has different options (including those for FastFlow).
