Function Documentation

Acts::InterpolatedBFieldMapper<Acts::detail::Grid<Acts::Vector2D, Acts::detail::EquidistantAxis, Acts::detail::EquidistantAxis>> Acts::solenoidFieldMapper(std::pair<double, double> rlim, std::pair<double, double> zlim, std::pair<size_t, size_t> nbins, const SolenoidBField &field)

Function which takes an existing SolenoidBField instance and creates a field mapper by sampling grid points from the analytical solenoid field.

Return

A field mapper instance for use in interpolation.

Parameters

  • rlim: pair of r bounds

  • zlim: pair of z bounds

  • nbins: pair of bin counts

  • field: the solenoid field instance
