Switching between four common stellar population synthesis models produces systematic offsets of up to 0.6 dex in stellar mass and 0.4 dex in star formation rate for the same galaxies.
Half of strong CIII] emitters at z=5-7 show secure AGN signatures, with median equivalent width rising 0.67 dex relative to z=3-4 galaxies.
