Effect on termination efficiency of kpause and kPE. The fraction of total TECs terminated (T) or run-off (TEC(i + 20)), when the rate constants for pause entry (A; kpause) or release (B; krelease) are varied. Units for the rate constants in the legend are s−1. When not varied kpause was set to 30 s−1 (B), while kPE and krelease were maintained at 0.01 and 1 s−1, respectively.
