_HADES_CLASS_DESCRIPTION


 calculate x,y (xPad,yPad) of a ring center on the Rich Padplane for a given theta and phi
 of a lepton track, Phi = 0: middle of the sector, sector edge: +-30°
 theta, phi in degree, x,y in mm, xPad, yPad in fraction of a pad
 target-center 5 mm downstream of rich-center (the latter normally shifted by about 35 mm upstream)
 Some transformations (angles2x, angles2xPad, xy2Phi,xy2yPad, xy2Theta, xy2yPadPad2x, zY2dTheta, zYPad2dTheta)
 are inline code implemented in hrichangles2xy.h. Refer to the '.h' file for full set of implemented transformations.
 Dependence on vertex position along the beam axis gives correction terms dy, dx or dyPad, dxPad.
 dx, dxPad are calculated simultaneously with dy, dyPad but called by special inline functions.
 The latter (zTheta2dx(), ztheta2dxPad() need a call to the corresponding functions zTheta2dy(), zTheta2dyPad() before.
 To correct for the vertex dependence of the theta, phi to y, x conversion requires to set the Rich Lab position (default -35 mm).
 This can be done via 'setRichPos(richLabPos)' function or by specifying a beamtime 'setRichPos("apr12")'
 Only Rich alignment for apr12, aug11 and sep08 is implemented by refering to beamtimes.
 The inverse Vertex correction deltaTheta calculated from z-vertex and x,y padplane is available as well.
 Version 2.0, Nov. 2013, W.Koenig
 V2.1: debugged V2.0, zTheta2dTheta added:
 correct Rich theta to match Track Theta as function of Vertex , Dec. 2013, W.Koenig
