Subject ： Two question about SAD

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.
