Detailed Description

Description: Plugin to create ideal tracker alignment records.

Implementation: The plugin takes the geometry stored in the global tag and transfers this information to the format needed in the TrackerAlignmentRcd. The APEs are set to zero for all det IDs of the tracker geometry and put into an TrackerAlignmentErrorExtendedRcd. In addition an empty TrackerSurfaceDeformationRcd is created corresponding to ideal surfaces.

An option exists to align to the content of the used global tag. This is useful, if the geometry record and the tracker alignment records do not match.
