Two extreme outliers identified in our sample, with reported electron temperatures of 70,000 K (top, NGC 628 region ID #179) and 30,000 K (bottom, NGC 2835 region ID #16). For each object we show the observed spectrum (black) the SSP model (grey), single Gaussian line fits (red) and fit residuals (dashed). The [N II]λ5755 line (left panels) is significantly detected and well fit. Both objects exhibit extremely broad Hα wings (right panels).
