Notes. (a) ``Y'' if the BCG is found in the low-entropy region and ``N'' if it is elsewhere. (b) even if the central entropy of this cluster is within the reach of AGN outbursts, it also shows some indications of on-going interaction and cannot be unambiguously associated to the ``AGN CC-remnant class'' (see text). (c) The BCG 2MASSX J09083238-0937470 is not associated to the CC-remnant, which however coincides with the position of the elliptical galaxy 2MASSX J09091923-0941591. (d) Due to the large indetermination of the metal abundance estimate, we could not unambiguously detect or exclude the presence of a metal abundance excess in this object.
