# global geometry file for the 2002 beam test
# Let Xl be a column matrix of x,y,z in the detector local system Sl
#     X  be a column matrix of x,y,z in the nominal test beam system S
# Then X is obtain from Xl using 3 (y-convention, passive) Euler angle
# rotations followed by a translation:
# X = R(psi)R(theta)R(phi)Xl + Xo
# Xo is therefore the coordinates of the origin of Sl in S
# Legend
# The first row is for the HEC, the second for the EMEC
# phi   (rad):  Euler angle rotation about zl :  Xl -> X'  = R(phi)Xl
# theta (rad):  Euler angle rotation about y' :  X' -> X'' = R(theta)X'
# psi   (rad):  Euler angle rotation about z'':  X''-> X'''= R(psi)X''
# x,y,z (cm) :  Xo translation in x,y,z       :  X'''-> X  = X''' + Xo
#
# nominal values (same of HEC and EMEC)
# phi       = 5pi/8
# theta     = pi
# psi       = 0
# x         = 0 cm
# y         = 171.8 cm
# z         = 298.3 cm

# updates:
# 03/06/13  nominal values (ML)
# 03/06/17  xl for HEC now same axis as for EMEC assuming nominal positions (ML)
