Normalized (to the maximum value of each data set) spatio-temporal emission plots obtained from wavelength integrated and wavelength selective PROES (columns) at various N_2 gas flows (rows). The powered electrode is located at x = 0, while the grounded electrode is located at x = 1 mm. The driving frequency, voltage amplitude, and the He flow are f = 13.56 MHz, φ = 315 V, and 1 slm, respectively.
