A full calibration of the spectrometers will be performed at the first stage of the experiment. It will include sieve-slit run calibrations for the angular reconstructions and kinematics calibrations for the momentum calibrations for both HKS and Enge, and other kinematics parameters such as absolute beam energy and central angles of spectrometers. The principle and analysis strategy for the spectrometers' calibration will be given in the following sections. In section 8.6, the general experimental procedures will be described.
