This file is foreseen for the Geometry module to replace Extent

Variables

static constexpr ActsScalar s_curvilinearProjTolerance = 0.999995

Tolerance for not being within curvilinear projection this allows using the same curvilinear frame to eta = 6, validity tested with IntegrationTests/PropagationTest.

static constexpr ActsScalar s_epsilon = 3 * std::numeric_limits<ActsScalar>::epsilon()

Tolerance for being numerical equal for geometry building.

static constexpr ActsScalar s_onSurfaceTolerance = 1e-4

Tolerance for being on Surface.

Note

This is intentionally given w/o an explicit unit to avoid having to include the units header unneccessarily. With the native length unit of mm this corresponds to 0.1um.
