YY等时线的CGI合成CMD计算器
A cgi synthetic CMD calculator for the YY Isochrones
摘要：
我们描述了一个基于Web的CGI计算器，用于使用Yonsei-Yale（YY）等时线数据库为简单的恒星星族（SSP）构建合成色星等图。这个计算器被设计为交互式使用。它创建快速查看CMD显示（B-V）和（V-I）颜色。包括对CMD的随机效应。表格形式的输出也可用于特殊用途的显示，或用于组合不同恒星星族的CMD。这一研究工具可用于研究银河系和外部系统的恒星含量。它提供了一个简单的方法来解释CMD在解决恒星星族。它提供了探索未解决的恒星系统的综合属性对恒星参数（年龄，化学成分，双星）和其母星人口的特征（IMF斜率和质量范围）的依赖性的手段。
英文摘要：
We describe a web-based cgi calculator for constructing synthetic color-magnitude diagrams for a simple stellar population (SSP) using the Yonsei-Yale (YY) isochrone data base. This calculator is designed to be used interactively. It creates quick look CMD displays in (B-V) and (V-I) colors. Stochastic effects on the CMDs are included. Output in tabular form is also provided for special purpose displays, or for combining the CMDs of different stellar populations. This research tool has applications in studies of the stellar content of our Galaxy and external systems. It provides an easy way to interpret the CMDs in resolved stellar populations. It offers the means to explore the dependence of the integrated properties of unresolved stellar systems on stellar parameters (ages, chemical composition, binarity) and on the characteristics of their parent population (IMF slope and mass range).
