Merged zero-order image over the entire exposure using a three-color, red, green, and blue, scheme reflecting the stars' energy spectra. The main image is shown with a 30″ scale covering about 60% of the entire captured ACIS-S field of view. The dispersive HETG first- and higher-order dispersion events of the brightest star θ ¹ Ori C were removed. The top right inset shows a wider view for 3′ with all dispersion streaks included. The most prominent ones are from θ ¹ Ori C. The bottom right inset shows a zoomed version of the Orion Trapezium region, which includes about 10 of the brightest stars in the region and for which we have the most significant HETG first-order spectra.
