Location of the NIRSpec detector gap for all IFU slices and affected gratings: G140H (top), G235H (middle), and G395H (bottom). For each slice of the IFU, the range of “missed” wavelengths is shown by a horizontal bar. The red vertical line in the bottom panel marks the position of the Hβ line for a target at z = 7.54. In this case, Hβ cannot be observed across half the field of view.
