ALMA Correlator Output (IMAGE) National Radio Astronomy Observatory Caption In this image, we see a screenshot of the full correlator output for a single one-second integration. The top two windows are the spectral shapes of the signals from the two individual antennas. The bottom ones are the phase (right) and cross-correlated power (left), which is a little less than one percent of the total.
