Fig. 3.

Completeness of our line detection criteria as a function of grism wavelength (probing Hα redshift) and Hα flux, for each field and survey. Top: FRESCO GOODS-N. Middle: FRESCO GOODS-S. Bottom: CONGRESS (GOODS-N). These show an asymmetric wavelength dependence due to the sensitivity curves and cross the 50% limit at log(f_Hα/erg s⁻¹ cm⁻²) ∼ −17.7.
