up to 5$\sigma$ emission line flux limits of $\mathrm{\sim3\times10^{-18}erg/s/cm^2}$ selected from deep NIR data $\mathrm{K_{AB}<25}$ obtained by the ZFOURGE survey.

ZFOURGE[^2] (PI I. Labbé) is a Ks selected deep 45 night photometric legacy survey carried out using the purpose built FourStar imager [@Persson2013] in the 6.5 meter Magellan Telescopes located at Las Campanas observatory in Chile. The survey covers 121 arcmin$^2$ in each of the COSMOS, UDS [@Beckwith2006], and CDFS [@Giacconi2001] legacy fields. Deep FourStar medium band imaging (5$\sigma$ depth of Ks$\leq$25.3 AB ) and the wealth of public multi-wavelength photometric data (UV to Far infra-red) available in these fields were used to derive photometric redshifts with accuracies $\lesssim1.5\%$ using EAZY [@Brammer2008]. Galaxy masses, ages, SFRs, and dust properties were derived using FAST [@Kriek2009] with a @Chabrier2003 IMF, exponentially declining SFHs, and @Calzetti2000 dust law. At $z\sim2$ the public ZFOURGE catalogues are 80% mass complete to $\sim10^9$[M$_\odot$]{}[@Nanayakkara2016]. Refer to @Straatman2016 for further details on the ZFOURGE survey.

ZFIRE and ZFOURGE are ideal surveys to use in this study since both provide mass complete samples. The total ZFIRE sample in the COSMOS field contains 142 [H$\alpha$]{} detected \[$>5\sigma$, redshift quality flag (Q$_z$)=3 \] star-forming galaxies that is mass complete down to
