Detailed Description

template<class POINT, class DIST2 = typename POINT::DR2>
class JetTiledMap::TiledEtaPhiMap< POINT, DIST2 >

An eta-phi map providing a relatively fast way of retrieving points at a given distance of a point in the plan (cylinder in this case). It works by simply dividing the plan in rectangular tiles of identical size and restricting the search only in a tile and its neighbours. IMPORTANT : the search is accurate only up to distance rmax where rmax is given to the init() function.
