摘要: We describe the coordinate systems of two streams HMI active region vector data. A distinction is made between (a) 2D grid on which field measured (or sampled), and (b) 3D established at each point, in presented. The data reduction can involve changes both, with those performed former termed "remapping", latter "vector transformation". Relevant pipeline procedures are described. Useful examples given for analysis.
