a Three RPI estimation of the core (in depth): NRM20mT/SIRM in green, NRM20mT/χ in red, and NRM20mT/ARM20mT in blue. b The PISO-1500 stack (blue) and Sint-2000 stack (red) for the last 750 ka (Channell et al. 2009). The black dashed line represents the threshold that appears to trigger excursions and reversals. Red dashed lines between up and down patterns correlate our RPI to the PISO-1500 stack
