From: Magnetic field compensation coil design for magnetoencephalography
Field angles to normal vectors of MSR walls In (a), boxplots of field angles to normal vectors of the MSR walls are depicted for 600 boundary points over the level of mirroring n. The angles the of fields of all 8 coils are included in the boxplots. The boxes are drawn around the region between the first and third quartiles, with a horizontal line at the median value. Whiskers extend from the box to the most distant values within 1.5 times the interquartile range. Outliers outside 1.5 times the interquartile range are marked with black dots. In (b), the angles of the fields to the wall normals at the 600 points are depicted over the according field magnitudes for mirroring level 7 and for each coil seperately.
