Detailed Description

Base class providing the boiler code to fill the Acts multi trajectory track states.

The states are filled with the n-dimensional local position & covariance, the source link to the ATLAS measurement and finally the projector is configured. A simple enum represents all tracking measurement configurations exisiting in ATLAS.

Member Enumeration Documentation

◆ ProjectorType

Enum encoding the possible projectors used in ATLAS.

Their integer representations correspond to the element index in the s_boundSpaceIndices member

Enumerator
e1DimNoTime 
e1DimRotNoTime 

Project out solely the locX (Applies to Itk strips, Rpc, Tgc, sTgc, Mm)

e2DimNoTime 

Project out solely the locY - Complementary projector if the strip plane is rotated (Applies to Itk endcap strips, Rpc, Tgc, sTgc)

e1DimWithTime 

Project out the two spatial coordinates - (Applies to ITk pixel, BI-Rpc, sTgc pad)

e1DimRotWithTime 

Project out the locX & time coordinate - (Applies to Rpc, Tgc, Mm, sTgc)

e2DimWithTime 

Project out the locY & time coordinate - (Applies to Rpc, Tgc, sTgc)
