Figure 5. Calculated flux density (summed over all frequencies) of TV radiation that would be measured over a sidereal day by an observer located in the direction of Barnard's star, third closest to the Sun and by chance near our celestial equator. The origin of the various peaks is indicated; <<rise>> and <<set>> refer , respectively to the appearance at western limb disappearance eastern of a particular region on rotating earth (n.a. north america ; w.e. europe ).
