(Cornell H. Mayer, "Radio Emission of the Moon...)

They deduced from their measurements that the radio_emission from the whole disk of the moon varied during a lunation in a roughly sinusoidal fashion ; that the amplitude of the variation was considerably less_than the amplitude of the variation in the infrared_emission as measured by Pettit and Nicholson ( 1930 ) and Pettit ( 1935 ) ; and that the maximum of the radio_emission came about 3 - 1 2 days after Full_Moon , which is again in contrast to the infrared_emission , which reaches its maximum at Full_Moon .

The maximum angular diameter of any planetary disk as observed from the earth is about 1 minute_of_arc .

This is much smaller than the highest resolution of even the very large reflectors now under construction , and consequently the radio_emission of different regions of the disk cannot be resolved .

Recent interferometer measurements ( Radhakrishnan and Roberts , 1960 ) have shown the 960 - Mc emission of Jupiter to be partially polarized and to originate_in a region of larger diameter than the visible disk .

The received radiation is compared with the radiation from a hypothetical black-body which subtends the same solid_angle as the visible disk of the planet .

(Raymond C. Binder et al., editors, Proceedings...)

The anode in figure 2 was mounted by means of the anode holder which was attached to a steel plug and disk .

Inflow of air from the surrounding atmosphere was prevented by the two disks shown in figure 2 .

Three thermocouples were placed at different locations in the aluminum disk surrounding the anode holder to determine its temperature .

The thermocouples in the aluminum disk shown in figure 2 indicated an equilibrium temperature of the surface of **f .
