################
Simple coherence
################


This example shows the estimated coherence between the differential-arm
length servo control loop error signal for LIGO-Hanford
(``H1:LSC-DARM_IN1_DQ``) and the motion of an optical periscope used to
direct the main laser beam into the Hanford interferometer, around the
time of |GW170814|.
