Starfinder程序是在稠密星星场中对典型的自适应光学结构的点扩散函数（PSF）进行天体测量和光度分析的第一次尝试。软件的最新版本还可以处理整个视场（FoV）的PSF变化。PSF可以从科学领域中最亮的恒星中提取数值，也可以在外部计算并以单个图像或图像立方体的形式作为输入提供。该功能使该软件适用于通过PSF重建技术获得的PSF模型。Starfinder还接受用户定义的参数模型和指向参数模型所需的PSF辅助数据的变量作为输入。该变量还可以包含关于FoV上的空间变化的信息。在本文中，我们描述了下一个版本的Starfinder报告也有一些例子，我们给出了使用变量PSF工具的配方。
The Starfinder code has been one of the first attempts to face with the typical adaptive optics structured Point Spread Function (PSF) in dense star fields to accomplish astrometric and photometric analysis. The last release of the software can also handle a variation of the PSF across the Field of View (FoV). The PSF can be either extracted numerically from the brightest stars in the science field or computed externally and provided as an input in the form of a single image or a cube of images. This feature makes this software suitable to work with PSF models obtained by PSF reconstruction techniques. Starfinder also accepts as an input a user-defined parametric model and a variable pointing the PSF auxiliary data required by the parametric-model. This variable might containing also information about the spatial variation across the FoV. In this paper we describe the next release of Starfinder reporting also some examples and we give the recipe to use the tool for variable PSF.
