Data from test series in the Electric Arc Shock Tube Facility were previously reportedfor velocities spanning 6-12 km/s in pure N2 at a freestream pressure of 0.2 Torr. The testseries provided spectrally- and spatially-resolved data for validation of a number of modelsof physical phenomena, including vibrational relaxation, molecular radiation, nitrogendissociation and ionization, and atomic radiation and ionization. In the present workanalysis of data obtained at a nominal velocity of 10.3 km/s is discussed in detail. Spectraare analyzed to extract temperatures and the densities of excited states as a function ofposition behind the shock. The effect of different methods for calculating state populationsand ionization processes is assessed, as is a rigorous assessment of the atomic line lists, withboth missing and extra lines identified.
