Notes. We report the parameters of the best-fit disks (top), and the differences in maximum-likelihood logarithm (
) and numberof degrees of freedom (d.o.f) between the disk models and the hypothesis that there is no emission associated with Vela X, and other models considered in the analysis (bottom). (a) Statistical uncertainty in the disk center position. (b)The multiple point source model has 11 sources associated with Vela X in the LE domain, and 3 in the HE domain. (c) We compare thebest-fit disks with the radio template in the LE range, and the H.E.S.S. template in the HE range, respectively. Section 2.2 provides details.
