Figure 13. These calculations model the simultaneous effects of vertical and radial overprints on the NRM. A. The x-component of NRM20mT - 0.01 · ARM; z-component of NRM20mT - 0.01 · ARM intensity. B. The x-component of NRM20mT - 0.01 · ARM; z-component of NRM20mT - 0.02 · ARM. C. The x-component of NRM20mT - 0.01 · ARM; z-component of NRM20mT - 0.03 · ARM.
