An Arai Plot is a simple, yet extremely effective, method for presenting data acquired from absolute paleointensity experiments
. In such graphs, the
remaining is plotted against the
gained at each temperature step. Given ideal behaviour, the slope of the straight line connecting all (or a segment) of the points is proportional to the intensity of the ancient magnetic field (i.e., B
= −Slope × B
). This is the most frequently used graphical plot for obtaining intensity estimates. Various parameters can be used to quantify the uncertainty and quality of the paleointensity estimate; these are discussed in the
