BPT diagrams for CSWA15 (upper) and CSWA165 (lower). Gray points are from individual pixels in each galaxy. Red points are from pixels whose values lie significantly above the maximum starburst line (green curve, Kewley et al. 2001). The region corresponding to the red points is shown in red in the map at the corner. The blue curve is the best fitted line for the ﹩z\sim 2.3﹩ samples in Steidel et al. (2014). Median values in uncertainties are shown in the purple error bars. A few pixels have large error bars, e.g., the data point at the top of the lower plot.
