RF patch cables and RCUs

Just a neat photograph today... this one was taken on the day of the official opening, looking across the patch cables going into the Receiver Unit (RCU) subracks.

The astute LOFAR observer will know that this is either an RCU mode 3 or mode 4 observation. (Because the led above all the middle input connectors is lit.) Indeed, we observed mode 3 riometry throughout that particular day.
