Editor’s note: This Astrobiology Fleet chart was shown by David Grinspoon and Shawn Domagal-Goldman on 22 Mar 2024 at an AAS Goddard Memorial Science Meeting. It is rather incomplete and […]

Examples of median-averaged IFU slices obtained with the G235M grating setting for Patroclus and Eurybates. The slices are projected onto the sky plane, with the x and y coordinates corresponding to right ascension and declination, respectively. A logarithmic stretch has been applied to the flux scaling in order to accentuate the detailed structure of the target PSFs at wide separations. The PSF of the Patroclus binary shows an extended shape. The black boxes denote the extraction regions used in producing the spectra. The faint background source near Patroclus lies in a region of the field of view that was masked during our spectral extraction. -- astro-ph.EP
