Member Function Documentation

constructHMatrix()

const AbsHMatrix * constructHMatrix ( const AbsTrackRep *  ) const

overridevirtualinherited

Returns a new AbsHMatrix object.

Caller must take ownership.

Implements AbsMeasurement.

Definition at line 120 of file SpacepointMeasurement.cc.

constructMeasurementsOnPlane()

std::vector< MeasurementOnPlane * > constructMeasurementsOnPlane ( const StateOnPlane &  state ) const

overridevirtualinherited

Construct MeasurementOnPlane on plane of the state and wrt the states TrackRep.

The state will usually be the prediction or reference state, and has to be defined AT the measurement. The AbsMeasurement will be projected onto the plane. It's possible to make corrections to the coordinates here (e.g. by using the state coordinates). Usually the vector will contain only one element. But in the case of e.g. a WireMeasurement, it will be 2 (left and right).

Implements AbsMeasurement.

Definition at line 69 of file SpacepointMeasurement.cc.

constructPlane()

SharedPlanePtr constructPlane ( const StateOnPlane &  state ) const

overridevirtualinherited

Contruct the virtual detector plane.

Per default, the plane will be constructed such that it contains the measurement and POCA to the measurement in cartesian space. The plane is perpendicular to the track (at the POCA).

If weightedPlaneContruction_ is set, the POCA will be calculated in a space weighted with the inverse of the 3D covariance. E.g. if the covariance is very oblate, the plane will be almost defined by the covariance shape. If the covariance is very prolate, the behaviour will be very similar to the ProlateSpacepointHit.

Implements AbsMeasurement.

Reimplemented in ProlateSpacepointMeasurement.
