An update of NEQAIR is presented and used to compare with experiment in the presence of thermal equilibrium. The updates included boundbound transition probabilities of C, N, and O, Stark broadening expressions, cross sections for bound-free transitions and additional transitions bands for N 2 . Moreover, the role of carbon contamination is examined. Some improvements are indicated but gaps remain between experiment and computation in the ultraviolet region of the spectrum. The discrepancies are not a result of ignoring the carbon contaminant.
