3.2″ across, north up, east left, resampled from the deepest mosaic covering the object in each band; ticks mark the catalogue position. Each band is stretched on its own noise; the composite shares one flux scale, so its colour is real. No coverage in F090W, F200W, F356W, F410M.

 

 

 

  

## Spectral energy distribution

  
- NIRCam wide
- 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. The gold line marks the Balmer limit (3646 Å rest) at z = 1.070.

## Redshifts

 

Each redshift keeps its own column. 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).

 | `z_vet` | Adopted by vetting | 1.0700 | z_agn

## Literature

 

Published objects within 1″ of this position. A match is a positional recovery, not an adopted classification.

 
- No published JWST little red dot or broad-line AGN within 1″.

 

 

 

 

 

## Photometry

 

Circular aperture of radius 0.16″ at each band's native resolution, background from a 0.40–0.65″ annulus, programmes combined by inverse variance. For a point source multiply by the field's aperture correction (r = 0.16″ → 0.70″). Grey rows are below S/N 2.
