Uniform and accurate photometric calibration plays an important role in the current next-generation wide-field imaging surveys. Herein, we review modern methods, including classic standard star method, “hardware/observation-driven" methods (such as Ubercalibration, Hypercalibration, Forward Global Calibration Methods), “software/physics-driven" (e.g., Stellar Locus Regression, Locus, Color Regr...

We present a method for creating simulated galaxy catalogs with realistic luminosities, broad-band colors, and projected clustering over large cosmic volumes. The technique, denoted ADDGALS (Adding Density Dependent GAlaxies to Lightcone Simulations), uses an empirical approach place galaxies within lightcone outputs of cosmological simulations. It can be applied significantly lower-resolution ...
