Each band is stretched on its own noise; the composite shares one flux scale, so its colour is real. No coverage in F090W. ## Spectral energy distribution - NIRCam wide - NIRCam medium - 2σ upper limit (S/N < 2) Aperture fluxes in a 0.16″-radius circle, not corrected to total; the values are in the photometry table below.

Photometric redshifts of little red dots are unreliable: against spectra, about a third of AGN-template redshifts (`z_agn`; 31 of 95 in the last purity run) and about half of galaxy-template redshifts at z > 3 were catastrophic outliers (methods Section 8). | Column | What it is | z | Source | `z_spec` | Spectroscopic, DJA grade 3 | 6.7286 | egs-nelsonx-v4_prism-clear_4106_47962.spec.fits | `z_vet` | Adopted by vetting | 6.7286 | zspec:dja_specz_grade3.csv:47962 | `z_phot` | Photometric (P(z) peak) | 6.614 | 68%: 5.603–7.661 | `z_bhs` | BH* channel fit | — | — | `z_agn` | Colour-lane fit | 7.25 | AGN-inclusive templates ## Spectral checks V-shape (spectrum)V-shaped Star (spectrum)no V-shape (photometry)fails βUV −1.77, βopt −2.31 at z_agn Line in F410MOIII 1 line-free optical band(s) Line-ambiguousyes Settling verdictLRD-like continuum ## Literature Published objects within 1″ of this position.
