a, Measured transmission spectra for all four instrumental modes as reported in the initial data release publications7,8,9,10. b, Measured transmission spectra at the native spectral resolution for NIRSpec PRISM and at one-fifth of the native spectral resolution for the other modes (Methods). c, Residuals of the synthesized data for each mode relative to a linear interpolation of the NIRSpec PRISM data, with coloured shading indicating the 1σ uncertainty bounds. Horizontal lines indicate the median difference relative to the SOSS (solid), F322W2 (dashed) and G395H (dotted) data. See Methods for a detailed quantitative discussion of the offsets between individual modes. Regions where the NIRSpec PRISM data experience saturation are marked in grey shading. These correspond to saturation after one (darkest) to four (lightest) groups. All displayed uncertainties correspond to 1σ.
