SETI@home: Spike Histogram Plots


This graph plots the number of spike detections at each frequency. Almost all of these detections are from noise. The three peaks at 1419, 1420 and 1421 MHz are due to test signals which are constantly injected to make sure the system is working. The fourth peak is due to radio frequency interference.

SETI@home looks for signals at 15 different bandwidths, each twice as coarse as the previous one. This plot shows the number of signals detected as a function of bandwidth.
