Convert a grid of (y,x) coordinates to an elliptical radius.

        If the coordinates have not been transformed to the profile's geometry, this is performed automatically.

        Parameters
        ----------
        grid : TransformedGrid(ndarray)
            The (y, x) coordinates in the reference frame of the elliptical profile.
