projector()

const std::uint64_t & xAOD::TrackMeasurement_v1::projector

(

)

const

The quantities measured by detector, are functions of the state vector, corrupted by a measurement noise.

However the state vector is normally not observed directly. The projector is mapping from the state vector to the mesured quantities. In our case the projector is linear, i.e. represented by a matrix of ‘ones’. The projector matrix is coded by the bits of "unsigned long long" variable and the conversion to/from matrix is done in Acts.
