| The Chris Cross at Fleurs |
| The Chris Cross, named after its designer, "Chris" Christiansen, was one of three pioneering telescopes at the Fleurs field station. The telescope had two 378-m long arms, oriented north-south and east-west, with each containing thirty-two 5.8m dishes. The Chris Cross operated at 1420 MHz, with a 1.5 arc-minute fan beam, and was initially used to generate two-dimensional high-resolution radio images of the Sun.
