template<typename source_link_t, typename parameters_t, typename covariance_t, typename indices_t, typename ...tail_indices_t>
auto Acts::makeMeasurement(source_link_t source, const Eigen::MatrixBase<parameters_t> &params, const Eigen::MatrixBase<covariance_t> &cov, indices_t index0, tail_indices_t... tailIndices) -> Measurement<source_link_t, indices_t, 1u + sizeof...(tail_indices_t)>

Construct a fixed-size measurement for the given indices.

This helper function can be used to create a fixed-size measurement using an explicit set of indices, e.g.

auto m = makeMeasurement(s, p, c, eBoundLoc0, eBoundTime);

Return

Fixed-size measurement w/ the correct type and given inputs

Template Parameters

• source_link_t: Source link type to connect to the detector readout

• parameters_t: Input parameters vector type

• covariance_t: Input covariance matrix type

• indices_t: Parameter index type, determines the full parameter space

• tail_indices_t: Helper types required to support variadic arguments; all types must be convertibale to indices_t.

Parameters

• source: The link that connects to the underlying detector readout

• params: Measured parameters values

• cov: Measured parameters covariance

• index0: Required parameter index, measurement must be at least 1d

• tailIndices: Additional parameter indices for larger measurements

for a 2d measurement w/ one position and time.

Note

The indices must be ordered and must be consistent with the content of parameters and covariance.
