Figure 20-27: A Recording of a Pulsar This chart recording shows the intensity of radio emission from one of the first pulsars to be discovered. (The designation PSR 0329+54 means pulsar at a right ascension of 03h 29m and a declination of +54°.) Note that the interval between pulses is very regular, even though some pulses are weak and others are strong.
