Cepheid Metallicity in the Leavitt Law Survey

The highly debated effect of metallicity on the absolute magnitudes of classical Cepheid variables needs to be properly quantified for determining accurate and precise distances...金属丰度（metallicity）对经典造父变星（classical Cepheid variables）绝对星等（absolute magnitudes）的影响备受争议，为实现准确且精密的距离测定，需对该效应进行合理量化。
