In order to reveal the second transition we carefully analyze the low-frequency part of the self-energy and the local spectral functions. This paper extends our previous work to lower temperatures. We discuss the nature - in particular the order - of both Mott transitions and list various possible extensions.4 pages, pss style; presented at conference "Physics of Magnetism", Poznan (Poland), June 24-27, 2005Strongly Correlated Electronstext
