在朝向银河系极点的方向上观测到的无线电频谱显示出接近5 Mc/s的最大值。似乎不太可能的同步加速器过程负责的排放可以给这样一个最大值，它建议，在较低的频率下，所观察到的流量密度下降是由平行于银道面的电离层的吸收。
The radio frequency spectrum observed in directions towards the galactic pole shows a maximum near 5 Mc/s. It seems unlikely that the synchrotron process responsible for the emission can give such a maximum and it is suggested that the observed fall in the flux density at lower frequencies is caused by absorption in an ionized layer parallel to the galactic plane.
