  1. Detected species with at least two consecutive emission line brightness over the detection threshold (3σ) from –200 ms to 120 ms, and at least one emission line brightness higher than 5σ. λi columns show the wavelengths (in nm). Aki columns show the atomic25 and molecular26 Einstein coefficients (in s−1). τki columns show radiative lifetimes (in s) of the related emission lines. Asterisks show blended lines. Middle dashes show unknown coefficients.
