1. The knob for coupling doesn’t give the expected correction
o Causes: the knob definition in the LSA database is wrong
o Diagnostic tools: the coupling doesn’t change as expected
o Remedies: the knob definition in LSA database has to be corrected
2. The bump at the experimental dipoles is not closed
o Causes: transfer function
o Diagnostic tools: orbit measurement
o Remedies: apply kicks on dipole compensators, adjust transfer function
