From: Asymmetry in the Earth’s magnetotail neutral sheet rotation due to IMF \(B_y\) sign?
Locations of the neutral sheet crossings in the GSM YZ plane for IMF \(B_z > 0\) conditions and different IMF \(B_y\) conditions after removal of the hinging and warping effects according to the T15 neutral sheet model. Left: T15 model (dataset M). Right: data (dataset O). GT = Geotail, TB = THEMIS-B, TC = THEMIS-C and C3 = Cluster 3. In each panel, N marks the number of the neutral sheet crossings, the blue line a linear regression and the angle \(\alpha\) the angle between the YGSM axis and the regression line indicating the rotation of the neutral sheet (increases from the positive YGSM axis toward the positive ZGSM axis). \(r^2\) is the quality indicator of the regression (square of the Pearson’s correlation coefficient). The ZGSM scale has been zoomed in to magnify the rotation
