Detailed Description

Abstract description of layers in a Vertex detector.

This assumes a symmetric layout of ladders, arranged in layers equidistant to IP.
The sensitive area is assumed to be inside the ladders but can be positioned independently.

virtual double gear::ZPlanarLayerLayoutImpl::getLadderLength ( int layerIndex ) const

inlinevirtual

The (half) length of the ladder in z direction in mm for ladders in layer layerIndex - layer indexing starting at 0 from the layer closest to IP.

Note: for historic reasons this is typically used to describe the half of the ladder in positive z, so it is the half length really.

Implements gear::ZPlanarLayerLayout.

virtual double gear::ZPlanarLayerLayoutImpl::getLadderOffset ( int layerIndex ) const

inlinevirtual

The offset of the ladder in mm defines the shift of the ladder in the direction of increasing phi perpendicular to the ladder's normal.

For example if the first ladder is at phi0==0 then the offset defines an upward shift of the ladder (parallel to the y-axis). Layer indexing starts at 0 for the layer closest to IP.
