Three-color images of COS-AGNi from GA-NIFS: Panel a. COS1118; Panel b. COS590; Panel c. COS1949; Panel d. COS349; Panel e. COS1656-A; and Panel f. COS1638-A (right) and -B (left). Red is the continuum, green is total [O III] emission, and blue is total Hα emission. For COS2949, green is total [N II] emission, to highlight the position of the AGN. Black crosses mark the position of the AGN. The continuum of COS1118, COS1656-A and COS2949 is measured over the full range probed by NIRSpec (≃3500−7000 Å for the first two, 6500−10 000 Å for the latter), after masking the emission lines. The continuum of COS1638-A and COS349 is measured in the ≃5500−6300 Å range because lower wavelengths are affected by strong Fe II emission. The continuum of COS590 is measured in the ≃3500–5200 Å range to exclude the noisier channels of the cube. For this target, we also subtract the field noise in the continuum map as the median of the signal for each pixel column.
