From: Using TNT-NN to unlock the fast full spatial inversion of large magnetic microscopy data sets
A comparison of spatial and frequency domain inversion results for the SVC982 speleothem showing a the SIRM magnetic moments found using the TNT-NN unidirectional inversion (dipoles oriented out of page) with 100 \(\upmu\)m dipole spacing, b the SIRM magnetic moments found using the Fourier technique of Lima et al. (2013) with 100 \(\upmu\)m dipole spacing (dipoles oriented out of page), and C the Fourier solution where only non-negativity constraint violations (undershoot) are shown (bottom). The field of view for all images is 50.1 mm \(\times\) 18.1 mm. All units are Am\(^2\)
