标题： Roman Observations Time Allocation Committee: Final Report and Recommendations

摘要： 罗马空间望远镜即将彻底改变我们对系外行星、暗物质、暗能量和一般天体物理学的科学理解，包括通过一种创新的社区方法来定义和执行天空调查。 罗马观测时间分配委员会（ROTAC）成立的目的是使用广域仪器（WFI）为三个核心社区调查（CCS）推荐时间分配：高纬度广域调查、高纬度时域调查和银河晕时域调查，以及平衡一般天体物理学调查的时间分配。 每个CCS都有一个对应的定义委员会，该委员会收集社区意见并设计了一个标准（在指南中）调查的提案，以及分别具有较小和较大时间分配的非指南和超指南选项。 这些选项探索了满足任务科学要求的不同方式，同时最大化由调查启用的一般天体物理学科学目标。 在本报告中，ROTAC提出了对三个CCS观测设计以及CCS的WFI时间分配（74.5%）和一般天体物理学调查（25.5%）的建议。 显示英文摘要

摘要： The Nancy Grace Roman Space Telescope is poised to revolutionize our scientific understanding of exoplanets, dark matter, dark energy, and general astrophysics, including through an innovative community approach to defining and executing sky surveys. The Roman Observations Time Allocation Committee (ROTAC) was convened to recommend time allocations for the three Core Community Surveys (CCS) using the Wide Field Instrument (WFI): the High Latitude Wide Area Survey, the High Latitude Time Domain Survey, and the Galactic Bulge Time Domain Survey, as well as balance the time allocation for the General Astrophysics Surveys. Each CCS had a corresponding Definition Committee that collected community input and designed proposals for a nominal (in-guide) survey, as well as underguide and overguide options with smaller and larger time allocations, respectively. These options explored different ways of fulfilling the mission science requirements while maximizing general astrophysics science goals enabled by the surveys. In this report, the ROTAC lays out its recommendations for the three CCS observing designs and the WFI time allotment for CCS (74.5%) and the General Astrophysics Surveys (25.5%).
