<radialGradient> element, this attribute defines the x-coordinate of the largest (i.e., outermost) circle for the radial gradient. The gradient will be drawn such that 100% gradient stop is mapped to the perimeter of the largest (i.e. outermost) circle. If the attribute is not specified, the effect is as if a value of 50% were set.

A <coordinate> is a length in the user coordinate system that is the given distance from the origin of the user coordinate system along the relevant axis (the x-axis for X coordinates, the y-axis for Y coordinates). Its syntax is the same as that for <length>.
