Explanation:
the point in an y vs. x or y vs. t (time) plot where y crosses the x c.q. t-axis; could also apply to a linear approximation of (part of a) curve; for a particular example, see wikipedia

the reason I gave a broad definition is because with a detector one could also asume it is the (extrapolated) x-value where the detector first starts to give a non-zero output (y)
