void CylinderGeomMicromegas::convert_to_planar ( uint  tileid,

convert g4hit coordinates from cylinder Micromegas to planar

this assumes that Micromegas Geant4 implementation are cylinders, while actual tiles are planes one must then 'drift' the g4hit along its momentum from its radius to the releval "y" in local coordinates
