WebMar 27, 2024 · The <010> axis forms a more diffuse point maxima, at approximately 90° to the <100> axis. The <001> axis forms a weak girdle maxima (where <001> data points lie on a great circle when plotted on lower hemisphere, equal area plots) where <001> is oriented in the ENE–WSW plane relative to reference frame of Figure 2 (Figure 3).
