0014 ##### The EPIC Detector Coordinate System definition
0015
0016 For EIC the hadron beam is going counter clockwise and the lepton beam clockwise.
0017 The hadron beam defines the positive z axis and x points to the ring inside as would be correct for a right handed coordinate system.
0018 * y-axis pointing to the sky
0019 * x-axis pointing to the ring inside
0020 * z-axis pointing along the ring in the direction of the hadron beam
0021 * The origin (0,0,0) of this coordinate system is at EIC IP-6.
0022 * The IP is in the EIC detector coordinate system at x=0, y=0, and z=0
0023 * The RHIC IP is in the EIC detector coordinate system at x= -80.9883cm, y=0, z= +13.77mm
