Member Function Documentation

const genf::GFDetPlane & genf::GFSpacepointHitPolicy::detPlane ( GFAbsRecoHit *  hit,
GFAbsTrackRep *  rep 
)

Get detector plane perpendicular to track.

The detector plane is contructed from the position of the hit and the track representation. For this the track is extrapolated to the point of closest approach to the hit.
