The study provides call letters, great circle distances and bearings, mid-point latitudes, range of vertical angles, 10% skywave field multiplier, horizontal plane radiation, maximum radiation within the range of vertical angles, and the night limit. The values of radiation from stations having directional antennas are based upon the pertinent calculated modified standard patterns (domestic) or notified patterns (foreign). Radiation values from non-directional stations are based on the notified antenna efficiency.
