Comparison of our measured resolution curves in the FS (emerald) and IFS (orange) modes with the pre-launch estimates from JDox (dashed gray lines). The shaded region around each resolution curve signifies the 1σ credible region. The in-flight resolutions are 11–53% higher than the pre-launch estimates in the FS mode, and 1–24% higher in the IFS mode (across the covered wavelengths).
