A 45-MHz continuum survey of the northern hemisphere

We present a survey of the 45 MHz radio continuum emission in the declination range +5degr to +65degr . The observations were made with the circular filled array of the Japanese Midle and Upper Atmosphere Radar with a half-power beam width of 3 <~ ^deg6. The results are presented in sets of maps in galactic and equatorial coordinates (Epoch 1950).
