Inversion results for the SVC982 speleothem: a an image of the SVC982 speleothem, b the SIRM B\(_z\) field map (the positive direction is out of page) obtained by scanning SQUID in nT with the color range scaled to show all the flood layers (the maximum intensity is 3256.4 nT), c the SIRM magnetic moments found using the TNT-NN unidirectional inversion (dipoles out of page) in Am\(^2\) with 100 \(\upmu\)m dipole spacing, and d the solution residuals in nT. The high-magnitude residuals located in the upper right of (d) are attributable to contamination present during scanning SQUID data acquisition. The field of view for the bottom three images is 50.1 mm \(\times\) 18.1 mm
