The HWS machine got rebooted so I restarted the code. I edited the code not to take new reference centroids but the tmux session didn't seem to recognize the change in the script so it ended up taking a new reference centroids anyway (to fix this issue I probably should have just exit the session and come back in). HWSX data starting from Tue, 21 Mar 2017 17:35:48 UTC now have new reference centroid taken during cold IFO (down time). All the optics were aligned.
