First we found strange low-frequency component in the BPM's signal. It could be came from the RF or we picking up some noise. When we started the actual calibration we noticed some phase jumps which was probably related to 'cooling problem' but around 4:00 AM these jumps disappears and we proceeded. We calibrated next BPM's:

• QM16FF x and y
• QM15FF x and y
• QM14FF x and y
• QM13FF x and y
• QM12FF x and y
• QM11FF x and y
• QD10BFF x and y
• QD10AFF x and y
• QF9BFF x and y
• QF9AFF x and y
• QF8BFF x and y
• QF8AFF x and y
• QF7BFF x and y
• QF7AFF x and y
• QF6BFF x and y
• QF6AFF x and y
• QF5BFF x and y
• QF5AFF x and y
• QF4BFF x and y
• QF4AFF x and y
• QF3BFF x and y
• QF3AFF x and y
• QF2BFF x and y
• QF2AFF x and y
