Caption: Figure 2.

Left: Stephan’s Quintet with KOSMOS slits overlaid to scale (underlying image same as Figure 1). Pink slits are observations taken along the major (slit PA = 150°) and minor (PA = 60°) axes of NGC 7319, and along the outflowing axis of the NLR (PA = 18°). Blue slits are observations along the minor axis but offset from the nucleus in increments of 2″. In these observations, the slits are adjacent but not overlapping. We obtained four observations offset to the southeast of the nucleus and five to the northwest. Right: a continuum-subtracted Hα image from HST Wide Field Camera 3 (WFC3) of the nuclear region of NGC 7319, with the nucleus-centered slits overlaid. The outflowing axis is still highlighted in pink, while the major and minor axes are in white.
