Figure 4
Graph (a): The horizontal axis is labeled “phi” and ranges from 0 to 1 in increments of 0.2 units. The vertical axis is labeled “tau” and ranges from 0.2 to 0.5 in increments of 0.05 units. A legend at the top left specifies that the graph shows two lines. One line with asterisk data markers represents “tau subscript c,” and the other line with square data markers represents “tau subscript t.” The “tau subscript c” line starts from (0, 0.25), rises to the upper right to end at (1, 0.5). The “tau subscript t” line starts from (0, 0.203), rises to the upper right to end at (1, 0.444). Graph (b): The horizontal axis is labeled “phi” and ranges from 0 to 1 in increments of 0.2 units. The vertical axis is labeled “theta” and ranges from 0.86 to 0.98 in increments of 0.02 units. A legend at the top right specifies that the graph shows one line with asterisk data markers that represents “theta.” The “theta” line starts from (0, 0.865), rises concave up to the upper right to end at (1, 0.968). Graph (c): The horizontal axis is labeled “phi” and ranges from 0 to 1 in increments of 0.2 units. The vertical axis is labeled “rho and Q” and ranges from 20 to 140 in increments of 20 units. A legend at the top left specifies that the graph shows two lines. One line with asterisk data markers represents “Q,” and the other line with square data markers represents “rho.” The “Q” line starts from (0, 109.412), rises slightly to the right to end at (1, 121.765). The “rho” line starts from (0, 40), descends slightly to the right to end at (1, 37.059). Graph (d): The horizontal axis is labeled “phi” and ranges from 0 to 1 in increments of 0.2 units. The vertical axis is labeled “f c and f t” and ranges from 2.5 to 6.5 in increments of 0.5 units. A legend at the top left specifies that the graph shows two lines. One line with asterisk data markers represents “f c,” and the other line with square data markers represents “f t.” The “f c” line starts from (0, 4.5), rises slightly to the upper right to end at (1, 6.266). The “f t” line starts from (0, 2.832), descends to the lower right to end at (1, 3.988). Graph (e): The horizontal axis is labeled “phi” and ranges from 0 to 1 in increments of 0.2 units. The vertical axis is labeled “pi subscript m” and ranges from 2600 to 3000 in increments of 50 units. A legend at the top left specifies that the graph shows one line with asterisk data markers that represents “pi subscript m.” The “pi subscript m” line starts from (0, 2623.415), rises slightly concave up to the upper right to end at (1, 2950). Graph (f): The horizontal axis is labeled “phi” and ranges from 0 to 1 in increments of 0.2 units. The vertical axis is labeled “pi subscript c and t” and ranges from negative 0 to 80 in increments of 10 units. A legend at the top left specifies that the graph shows two lines. One line with asterisk data markers represents “pi subscript c,” and the other line with square data markers represents “pi subscript t.” The “pi subscript c” line starts from (0, 23.024), rises slightly concave up to the upper right corner to end at (1, 70.634). The “pi subscript t” line starts from (0, 4.683), rises slightly concave up to the right to end at (1, 29.81).
