One-dimensional spectrum of Source 1 at z = 2.41 extracted from the aperture shown in Figure 1. The same aperture was used to compute the JWST/NIRcam, NIRISS, and Hubble photometry, all superimposed on this figure without applying any scaling factor. At the bottom, the filter names are indicated with the magnitudes of Source 1. The blue dashed lines show the filter throughputs. The green region shows the noise obtained from 62 spectra extracted with the same aperture size, placed randomly in the field of view. The blue and red lines show the absolute and standard deviation from the green envelope.
