Here we provide the NIRSpec prism composite spectra constructed in Roberts-Borsani et al. (2024), stacked as a function of redshift, absolute magnitude, and stellar mass (see Sections 2 and 3 for details). The spectra are contained within two tar files, one containing the composites in Table 2 of Roberts-Borsani et al, and one containing continuously-updated composites as prism data become available, using the same procedures and stacking criteria described in the paper. In addition, we also include the (continuously-updated) composite from Figure 3 of the paper, which is not used in the analysis.

Updated composite spectra from the paper [last update 13/03/2024] : Coming soon
The composites have names, redshifts, and inferred properties as listed in Table 2 of Roberts-Borsani et al. (2024). Each have five columns:
[column 1] : Observed wavelength (in Angstroms)
[column 2] : Spectral fluxes (in nJy)
[column 3] : 1σ uncertainties (semi-difference of the 16th-84th percentiles divided by SQRT(N)). Same units as column 2.
[column 4] : The same as column 3 but with artificially-boosted uncertainties over strong emission lines. Same units as column 2.
[column 5] : The spread of the data (from the semi difference of the 16th-84th percentiles). Same units as column 2.
We also provide separately the average (wavelength-dependent) slit loss correction function from the paper (see Appendix B and Figure 13), which consists of two columns:
[column 1] : Observed wavelength (in microns)
[column 2] : The multiplicative factor to apply to the prism spectrum.
