Survey simulation output files, presented at the May 2024 "Science with NEO Surveyor" Workshop in San Diego, CA, USA

Included here are output files from a series of simulations run using the NEO Surveyor Survey Simulation tool. These files were first provided to the community at the Science with NEO Surveyor Workshop in San Diego, CA, in May 2024. Each simulation has three output files: *_props.tbl which gives the properties of the input population for the simulation, including name, size, geometric V-band albedo, absolute magnitude, and orbital parameters *_flux.tbl which provides detection information for each object that would have been detected by NEO Surveyor, including its NC1 and NC2 magnitudes and SNRs, as well as earth-to-spacecraft position vector at the time of detection; these data are intended to be analogous to what would be provided from the detection tables that will be archived with IRSA *_geom.tbl which provides the heliocentric distance, observer distance, and phase angle for each object at each detection; these data are to facilitate thermal modeling, assuming perfect orbit knowledge The populations simulated here are: NEO_SSR1: A simulated population of 25,000 NEOs with size of 140m and larger 50m_60m_NEO_SSR1: A simulated population of 10,000 NEOs with sizes between 50 and 60 m small_MBA_SSR_0000: A simulated population of ~10,000 main belt asteroids with sizes ranging from 400m to 10km neos_of_interest: A selection of 13 real NEOs with known or assumed properties mbas_of_interest: A selection of 28 real MBAs with known or assumed properties comets_of_interest: A selection of 7 real comets with known or assumed properties (note, fluxes provided are nucleus-only) Two other files are provided: photo_params.dat which provides the current best estimate (as of May 2024) for the values of the magnitude zero-points and band centers for each band neo_surveyor_pointing_list.dat which provides a sequence of field centers, solar elongations, and spacecraft positions and velocities for the nominal survey pattern and orbit used for the simulations Acknowledgment: If you use any of these data products for a publication please cite Mainzer et al. 2023, PSJ, 4, 224, doi:10.3847/PSJ/ad0468, and include the following acknowledgment: "This publication makes use of software and data products from the NEO Surveyor mission, which is a joint project of the University of California, Los Angeles and the Jet Propulsion Laboratory/California Institute of Technology, funded by the National Aeronautics and Space Administration."本数据集包含使用近地天体巡天望远镜（NEO Surveyor）巡天模拟工具运行的一系列模拟任务的输出文件。这些文件于2024年5月在加利福尼亚州圣迭戈举办的“NEO巡天望远镜科学应用”研讨会上首次向学界公开。 每个模拟任务均生成三类输出文件： *_props.tbl：记录本次模拟输入天体族群的各项属性，包括天体名称、尺寸、几何V波段反照率、绝对星等以及轨道参数。 *_flux.tbl：提供所有可被近地天体巡天望远镜探测到的天体的探测信息，包括其NC1、NC2波段星等与信噪比（SNR），以及探测时刻的地球-航天器位置矢量；此类数据的设计逻辑与未来将由红外科学档案中心（IRSA）归档的官方探测数据表保持一致。 *_geom.tbl：提供每个探测时刻天体的日心距离、观测者距离与相位角，用于在已知精确轨道的前提下开展热学建模。 本次模拟涵盖以下天体族群： - NEO_SSR1：包含25000颗直径不小于140米的近地天体（NEO）模拟族群 - 50m_60m_NEO_SSR1：包含10000颗直径介于50至60米之间的近地天体模拟族群 - small_MBA_SSR_0000：包含约10000颗直径范围为400米至10千米的主带小行星（MBA）模拟族群 - neos_of_interest：精选的13颗具有已知或推定属性的真实近地天体 - mbas_of_interest：精选的28颗具有已知或推定属性的真实主带小行星 - comets_of_interest：精选的7颗具有已知或推定属性的真实彗星（注：本次提供的光度数据仅对应彗核） 此外还提供两个附加文件： 1. photo_params.dat：提供截至2024年5月的最新最优估算值，涵盖各波段的星等零点与波段中心参数。 2. neo_surveyor_pointing_list.dat：提供本次模拟所采用的标准巡天模式与轨道对应的一系列视场中心、太阳张角以及航天器位置与速度参数。 致谢说明：若您将本数据集用于学术出版，请引用Mainzer等人2023年发表于《行星科学期刊（Planetary Science Journal, PSJ）》第4卷第224页的论文，DOI:10.3847/PSJ/ad0468，并补充以下致谢语："This publication makes use of software and data products from the NEO Surveyor mission, which is a joint project of the University of California, Los Angeles and the Jet Propulsion Laboratory/California Institute of Technology, funded by the National Aeronautics and Space Administration."
