Starshade Imaging Simulation Toolkit for Exoplanet Reconnaissance (SISTER) is a versatile tool designed to provide accurate models of the images of exoplanet systems when observed with a starshade positioned to block the light from the host star. SISTER allows one to control a set of observational parameters including: (1) the starshade design, position, orientation, and glint properties; (2) the telescope and optical system pupil, aberrations, bandpass, and throughput including a detector model; (3) the exoplanetary system, including stellar distance and spectral type, parallax and proper motion, planet size, reflection properties, orbital parameters, and exozodiacal dust; and (4) background objects. Additionally, there is a substantial library of built-in plotting software added, but the simulations may be stored on disk and plotted with any other software. We describe SISTER’s algorithms, its operational modules, and how it can be used to generate starshade optical simulations with a high degree of fidelity. We include some imaging examples.

用于系外行星侦察的Starshade成像仿真工具包

用于系外行星侦察的Starshade成像仿真工具包（SISTER）是一种多功能工具，旨在在定位有遮蔽主恒星的光的恒星阴影时为系外行星系统的图像提供准确的模型。SISTER可以控制一组观测参数，包括：（1）星状阴影的设计，位置，方向和闪光特性；（2）望远镜和光学系统的光瞳，像差，带通和通过量，包括探测器模型；（3）系外行星系统，包括恒星距离和光谱类型，视差和适当运动，行星大小，反射特性，轨道参数和系外行星尘埃；（4）背景物体。此外，还添加了大量的内置绘图软件库，但是模拟可以存储在磁盘上，并可以与任何其他软件一起绘制。我们将介绍SISTER的算法，其操作模块，以及如何将其用于生成高保真度的星状阴影光学模拟。我们包括一些成像示例。
