J. Kissel, NOVA Film Crew

I've modified the main displays on the front wall at the request of the NOVA film crew. The lower screen is displaying the GW150914 waveform and the background of the DTT session showing the Live Sensitivity on the Upper screen has been changed to black.

There is zero intention of this being permanent, but I figure there will be no harm in leaving it as such over the weekend since the content normally displayed on these screens only has meaning when we have light in the arms, no one is intending to commission the corner station over the weekend, and there'll be no operations specialists on shift over the weekend. So, it should just be the film crew, Dr. Levin, and their site liaison, and they all want it this way!

I'll restore the displays to normal Monday.
