The horizontal axis lists “Low T C” and “High T C”. The vertical axis is labeled “B P” and ranges from 1 to 5 in increments of 1 unit. Two lines are plotted and labeled in the legend as “Low C S C” and “High C S C”. The “Low C S C” line begins near 2.9 B P at Low T C and decreases slightly to 2.75 B P at High T C. The “High C S C” line begins at 3 B P at Low T C and rises to about 3.5 B P at High T C. The gap between the two lines widens at High T C. Note: All numerical values are approximated.
