[$\mathrm{log_{10}(M_*/M_\odot)}$]{}$>9.30$ (at 80% for $Ks=24.11$). Thus, our [H$\alpha$]{} selected sample contains no significant systematic biases towards SFH, stellar mass, and magnitude. Furthermore, ZFIRE contains a large cluster at $z=2$ containing 51 members with $5\sigma$ [H$\alpha$]{} detections [@Yuan2014] and therefore we are able to examine if the IMF is affected by the local environment of galaxies.

For this study, we apply the following additional selection criteria to the 142 [H$\alpha$]{} detected galaxies.\
$\bullet$ We remove active galactic nucleus (AGN) using photometric [@Cowley2016] and emission line ($\mathrm{log_{10}}$(f([\[\]]{})/f([H$\alpha$]{}))$>-0.5$; @Coil2015) criteria resulting in identifying 26 AGN with our revised sample containing $N=116$ galaxies. We note that all galaxies selected as AGN from ZFOURGE photometry by @Cowley2016 are flagged as AGN by the @Coil2015 selection. We further discuss contamination to [H$\alpha$]{} from sub-dominant AGN in Appendix \[sec:AGN\].\
$\bullet$ Galaxies must have a matching ZFOURGE counterpart such that we can obtain galaxy properties, resulting in N=109 galaxies.\
$\bullet$ We compute the total spectroscopic flux for these galaxies and remove 4 galaxies with negative fluxes resulting in N=105 galaxies. We perform stringent [H$\alpha$]{} emission quality cuts to the spectra for these 105 galaxies and remove 2 galaxies due to strong sky line subtraction issues. We further remove
