AB: By using the elliptic cone model as a geometric proxy of the CME flux rope structure, we have established an one- point approach to invert geometric properties of frontside disk full-halo CMEs, such as the CME propagation direction, shape and angular widths. This work presents an algorithm for determining the radial speed and acceleration of full-halo CMEs on the basis of the apparent speed and acceleration observed on the sky-plane. Since there is some uncertainty in the one-point determination of the CME propagation direction, this work provides a way to estimate the confidence level of the inverted elliptic cone model parameters.
