摘要:

本文件描述了宽视场红外巡天望远镜(WFIRST)高纬度巡天的曝光时间计算器。计算器在成像和光谱模式下工作。除了标准的ETC功能(例如背景和S/N确定),计算器还对星系人口进行积分,并预测可用于弱透镜(成像模式)和检测到的发射线(光谱模式)的星系形状的密度和红移分布。源代码可供公众使用。

英文摘要:

This document describes the exposure time calculator for the Wide-Field Infrared Survey Telescope (WFIRST) high-latitude survey. The calculator works in both imaging and spectroscopic modes. In addition to the standard ETC functions (e.g. background and S/N determination), the calculator integrates over the galaxy population and forecasts the density and redshift distribution of galaxy shapes usable for weak lensing (in imaging mode) and the detected emission lines (in spectroscopic mode). The source code is made available for public use.
