Figure 14. T-jump-induced tension transients extracted from combined transients by subtraction of mechanical transients induced by length step release.

Three-exponential fittings of the tension transients induced by length step releases at low and high temperature shown in Fig. 14 were subtracted from the complex transients shown in Fig. 13 and offset up by the value of elastic response. The fits were used instead of the transients to reduce noise and to have extrapolations longer than the records. The fit of low-temperature mechanical transient (trace 6 in Fig. 13) was subtracted from traces 7 and 8 in Fig. 12, while the fit of high-temperature transient (trace 7 in Fig. 13) was subtracted from traces 10–13. Isometric trace 9 was not changed.
