Direct comparison of MRS-observed Hα emission-line profile for galaxies E (top) and W (bottom), with the rescaled Hβ narrow- and broad-line components identified in lower spectral resolution NIRSpec IFS (Jones et al. 2024). The presence of the narrow plus broad components could be compatible with the observed Hα line profile (see Sect. 4.5 for a detailed discussion). The systemic velocity corresponds to redshift 7.1513. The residuals are shown in the bottom plots, together with the 1σ noise level (yellow).
