The surface brightness distribution is not only described by a spherically symmetric model but also by a two-dimensional $\\beta $-model fit. Subtracting an elliptical model cluster as defined by the best fit parameters of the two-dimensional model we find significant residuals, indicating an additional, extended X-ray source within the cluster.
