Long Term Variations of Pulsar Intensities
PULSAR intensity variations may be divided roughly into three classes. There are rapid variations on a time-scale of seconds to minutes which occur simultaneously over a wide range of frequency and must therefore be intrinsic to the source 1 . On a somewhat longer time-scale there are variations typ...
