Fig. 5From: Non-monochromatic whistler waves detected by Kaguya on the dayside surface of the moonAn example of the minimum variance method applied to the period 5:24:0–5:24:8. Top: the direction of the minimum variance (thick bars) and the average magnetic field (thin lines) projected onto the x-y and x-z plane of the SSE coordinates. Bottom: The hodograms of the magnetic field. The minimum, medium, and maximum variances were 0.15, 0.59 and 0.73, respectively.Back to article page
