parameters
2 Calculation of
epfd levels at radio astronomy sites
2.1
Definition of epfd
Annex 2 Distribution of epfd levels
1 Division of the
sky into cells of approximately equal solid angle
2 epfd
distribution for a cell
3 epfd
distribution in worst‑case pointing directions (to be applied only if the
pfd levels from satellites are constant for a given elevation angle of radio
astronomy service antenna)
4 Output in terms
of epfd distribution
