Cartesian coordinate systems, the y-coordinate (y2) for the doublet refers to the vertical position of the doublet source (or sink) along the y-axis. The y-axis is one of the two perpendicular axes in a Cartesian coordinate system, typically representing the vertical direction. For a doublet located in a Cartesian coordinate system with its center at the origin (0, 0), the y-coordinate (y1) specifies the vertical distance from the origin to the position of the doublet source (or sink).Â
