IMC HEPI current position
HAM2 and HAM3 HEPI are currently locked. IO requested a survey of the shift between the current position of HEPI, and its controlled position during a recent IMC lock: October 5th 2013, 9am to 10am.
We looked at the IPS readouts to track the position of HEPI. The following script was created for calibration and coordinate transform of the signals: /ligo/svncommon/SeiSVN/seismic/HEPI/H1/Common/HEPI_Shift_Cart.m
