The attached table shows the amplitude of the green beat note when the end laser was in various states. We can increase the beat note amplitude dramatically by switching to a different states.

State 1
C1:GCX-GRN_REFL_DC:             638 counts
C1:GCV-XARM_BEAT_DC: (PSL blocked)    950 avg counts (zero = -794 counts)
amplitude of beat note:            -23dBm (after PD + amps) (f ~ 30 MHz)?
C1:GCX-SLOW_SERVO2_OUT:            318 counts

State 2
C1:GCX-GRN_REFL_DC:             180 counts
C1:GCV-XARM_BEAT_DC: (PSL blocked)    1270 avg counts (zero = -794 counts)
C1:GCV-XARM_BEAT_DC: (PSL unblocked)    1700 avg counts (zero = -794 counts)
amplitude of beat note:            -7dBm (after PD + amps) f = 60MHz
amplitude of beat note:            0dBm (after PD + amps) f = 30MHz
C1:GCX-SLOW_SERVO2_OUT:            290 counts

State 3
C1:GCX-GRN_REFL_DC:             220 counts
C1:GCV-XARM_BEAT_DC: (PSL blocked)    1120 avg counts (zero = -794 counts)
C1:GCV-XARM_BEAT_DC: (PSL unblocked)    1520 avg counts (zero = -794 counts)
amplitude of beat note:            0dBm (after PD + amps) f = 15MHz
C1:GCX-SLOW_SERVO2_OUT:            305 counts

PSL temp = ??
C1:PSL-FSS_SLOWM = -3.524
