摘　　要：均匀且精确的流量定标是大视场测光巡天的难点和成功的关键因素之一.本文总结了当前大视场巡天流量定标方法的发展情况,包括经典的标准星方法,“硬件驱动/观测驱动”的Ubercalibration,Hypercalibration,Forward Global Calibration方法,及“软件驱动/物理驱动”的Stellar Locus Regression,Stellar Locus及Stellar Color Regression方法,并对这些方法的优势、限制及其后续发展,特别是Stellar Color Regression方法,进行评述与讨论.Uniform and accurate photometric calibration plays an important role in the current and next-generation wide-field imaging surveys.Herein,we review the modern photometric calibration methods,including the classic standard star method,“hardware/observation-driven”methods(such as the Ubercalibration,Hypercalibration,and Forward Global Calibration Methods),and“software/physics-driven”methods(e.g.,the Stellar Locus Regression,Stellar Locus,and Stellar Color Regression Methods).Further,we discuss their advantages,limitations,and future developments toward millimagnitude precision calibration.
