Spatial distributions of the harmonic waves observed by Kaguya. The observed locations (a) in the Selenocentric Solar Ecliptic (SSE) coordinates with SZA contours shown for every 20° and (b) in the selenographical (Mean Earth/polar axis, ME) coordinates. The gray and black contours in ME coordinates indicate 0.25- and 0.5-nT magnetic field strength at 100-km altitude, respectively. The sizes and colors of the points correspond to the number of harmonics and total intensities of the fundamental waves, respectively. The occurrence rate distributions of the harmonic waves in (c) SSE and (d) ME coordinates. The superpositions of the occurrence rate distributions of the harmonic waves (hr) and the narrowband waves (nr) in (e) SSE and (f) ME coordinates.
