[ns] Default energy consumption in NS2

[Salvo Danilo Giuffrida]

I'm not able to find the default values for mobile node's energy
consumption (rxPower/txPower) in NS2...I've looked into
ns-default.tcl, inside the C++ code, I even tried using 'find', but
there's no value (apart from a 0 in the constructor of the C++ class
EnergyModel). Do you know where I can find them, and what's their
value?
Thanks
