tokens: constructs mock catalogs including both photometry and morphologies. Similar to JAGUAR, EGG uses empirical prescriptions, starting with a derivation of the evolution of the stellar mass function from deep observations. In this section, we compare the recovered TPD, completeness, and accuracy for the EGG catalog to what we found using the JAGUAR catalog. A few of the primary differences between JAGUAR and EGG that will influence the present analysis are the evolution of the stellar mass function, the treatment of galaxy morphologies and dust obscuration, and the inclusion of self-consistent nebular continuum and line emission. The EGG team started with a framework for the evolution of the star-forming and quiescent galaxy mass function at z = 0.3–4.5 based on observations from CANDELS (Grogin 2011 ; Koekemoer 2011 ), where they computed photometric redshifts using EAZY (Brammer et al. 2008 ) and galaxy stellar masses using FAST (Kriek et al. 2009 ). At z = 4.5–7.5, the authors rely on the stellar mass functions from Grazian et al. ( 2015 ). The resulting mass function evolution has a steeper low-mass slope than the prescription that underpins the JAGUAR catalog at z > 1.5, and the discrepancy is larger at higher redshifts. In addition, the evolution of the EGG mass function predicts fewer high-mass galaxies at z > 4 than JAGUAR. Both of these differences are likely a consequence of the necessary extrapolation that was done for each catalog due to lack of observational data. The SEDs in EGG were generated by first assigning a U − V and V − J color to each mock galaxy based on the observed evolution of these colors for star-forming and quiescent galaxies. At this point, each mock galaxy was given an SED based on the average SED for observed CANDELS galaxies with those UVJ colors (from the FAST fits, using the Bruzual Charlot 2003 stellar library). As the morphology of each EGG mock galaxy is defined to be a combination of a bulge and disk component, each component was assigned a separate SED. This process differs significantly from the SED creation in JAGUAR, which uses BEAGLE fits to 3D-HST objects to calculate the SEDs for each object. In the version of the EGG catalog generation tool we used in this analysis, v1.4.0 ( egg-gencat ), the authors included a simple prescription for emission lines, where the strength of each line is estimated using each mock galaxy’s SFR, metallicity, total infrared luminosity, and gas mass, 15 15 See: https://github.com/cschreib/egg/blob/master/CHANGELOG . which we include to better compare to JAGUAR. We used egg-gencat to create two catalogs, one with 100 square arcminutes and one with 10.8 square arcminutes, with a minimum stellar mass of 10 6 M , at z = 0.2–15. We then constructed 500 noisy catalogs with each area in the exact manner as was done in Section 2.2 for the JAGUAR catalogs, although we modified this process to account for the combination of the disk and bulge components in each EGG mock galaxy.
