Schematic diagram of the three filament directions and the corresponding P-V diagrams. The extraction paths follow the filament directions indicated in the upper-left panel, with widths chosen to encompass the full spatial extent of each filament. The red, white, and green paths correspond to X1, X2, and X3, with integration widths of 90′, 70′, and 50′, respectively.
