Hello, I have two questions about SAD:
1) What is the exact definition of key word MOMENTUM? I guess it should be MOMENTUM=\gamma_0*m_0*v_0*c, but not \gamma_0*m_0*c^2. Say, MOMENTUM=4.0 GeV for SuperKEKB LER. Am I right?
2) I found the k64 branch of SAD gives different closed orbits from that of normal version in the longitudinal direction (z and delta) around the ring for sher_5764. In the SAD computers, I run: k64 branch: /SAD/bin/gs -k64 normal version: /SAD/bin/gs What makes the differences?
Thanks in advance.
