Every magnet held the own nominal part frame with different

main ring (CSRm) and experimental ring (CSRe). The
circumference of CSRm and CSRe is 161m and 128.8m

them in the SA. Best-fit actual data to nominal data in the
nominal part frame, we can get the 7 parameters: ΔX, ΔY, ΔZ,
Δφ, Δψ, Δω and Scale respectively, these parameters imply if the
magnet need to be adjusted（see Figure 3 and Figure 4).
