Times in the figure are observer times, which are shorter than the tabulated reaction times by a factor equal to the density ratio across the shock front.

SENSITIVITY DIAGRAMS

The sensitivity spectra shown below were computed with a trial reaction mechanism composed of a set of 322 elementary reactions of 53 species.
