First Fringes of LOFAR CS1 station
| Submitter: | LOFAR Project |
| Description: | the LOFAR project proudly presents the first fringes observed with the CS1 station and correlation in Groningen. These fringes prove the functioning of the integrated signal flow from the antennas and signal processing in Exloo through the fiber connection to Groningen and correlation on the Blue Gene supercomputer. This observation marks the start of the scientific comissioning campaign. The figures show the cross correlation of two dipoles over a period of 4 hours. The dipoles have an almost east-west baseline of 34 meters. Shown is a single frequency channel of 1 kHz around 60 MHz integrated over 1 minute. The top plot shows the real part of the correlation, nicely following a sine shape. The lower plot shows the phase angle rotating over three periods |
