Broadband spectrum of GN-9771 in comparison to other LRDs. We have highlighted the main emission lines on the top axis. We make a comparison with the PRISM spectrum of the other LRDs in our IFU program (Matthee et al. in prep.) and of A2744-45924 (Labbe et al. 2024), after normalizing their flux to match GN-9771 in the 5400–5700 Å band. The spectrum of GN-9771 is very similar to the spectrum of A2744-45924, with only a slightly weaker Balmer break in the case of GN-9771.
