Empirically derived emission line (top) and continuum (bottom) sensitivities for the Wide survey as a function of disperser and observed wavelength. The solid lines are the 5-σ sensitivities for a centered point source, while the dashed lines are the 5-σ sensitivities for an “extended” source, namely a centered object with a Sersic index n = 1 and a half-light radius of 0$\stackrel{″}{.}$3 (a typical star-forming galaxy at z ≈ 1.5; van der Wel et al. 2014).
