Notes. The first and second column represent the abundances obtained by untying the warm plasma component from the cooler and hot components, which are tied to teach other. The third and fourth columns represent the abundances obtained by untying the hot plasma component from the cooler and warm components, which are tied to teach other. The fifth and the sixth column represent the same obtained by untying the cooler plasma component from the warm and hot components, which are tied to each other.
