The Data for 'Impact of Systematic Modeling Uncertainties on Kilonova Property Estimation'

Produced synthetic kilonova spectra for 'Impact of Systematic Modeling Uncertainties on Kilonova Property Estimation' using the Sedona radiative transfer code. Each model is an h5 file with the following groups: Lnu - Array of length # of timesteps by # of frequency bins that contains the spectral sequence of each kilonova model in cgs units (erg/s/Hz) click - Array of length # of timesteps by # of frequency bins for the number of Monte Carlo particles that make up Lnu mu - Center of polar angular bins (not useful since simulations are 1D) mu_edges - Edges of polar angular bins (not useful since simualtions are 1D) nu - Array of length # of frequency bins that are the central frequencies of a bin (Hz) nu_edges - Array of length # of frequency bins +1 that are the edges of each frequency bin (Hz) phi - Center of azimuthal angular bins (not useful since simulations are 1D) phi_edges - Edges of azimuthal angular bins (not useful since simulations are 1D) time - Times at which each spectrum was generated (Days) time_edges - Edges of time bins (Days) Each kilonova spectra file is named according to <atomic dataset>_<thermalization prescription>_KN_<lanthanide fraction>X_lan_<characteristic velocity>v_<mass>M_1D_spec.h5 where: atomic dataset is one of: HULLAC, ATOMIC, or Autostructure thermalization prescription is one of: local or global lanthanide fraction is the fraction of lanthanides in the ejecta by mass characteristic velocity is the kinetic velocity of the ejecta in units of the speed of light mass is the mass of the ejecta in units of solar masses本数据集针对《系统建模不确定性对千新星（kilonova）性质估算的影响》一文，采用Sedona辐射转移代码生成了合成千新星光谱。每个模型均为h5格式文件，包含以下数据组： Lnu：维度为【时间步数×频率通道数】的数组，存储各千新星模型的光谱序列，单位为厘米-克-秒（cgs）制，具体为尔格/秒/赫兹（erg/s/Hz）。 click：维度为【时间步数×频率通道数】的数组，记录构成Lnu光谱的蒙特卡洛（Monte Carlo）粒子数目。 mu：极角分箱的中心（因模拟为一维，无实用价值）。 mu_edges：极角分箱的边界（因模拟为一维，无实用价值）。 nu：长度等于频率通道数的数组，存储各频率分箱的中心频率，单位为赫兹（Hz）。 nu_edges：长度为【频率通道数+1】的数组，存储各频率分箱的边界，单位为赫兹（Hz）。 phi：方位角分箱的中心（因模拟为一维，无实用价值）。 phi_edges：方位角分箱的边界（因模拟为一维，无实用价值）。 time：生成各光谱对应的时刻，单位为天（Days）。 time_edges：时间分箱的边界，单位为天（Days）。 每个千新星光谱文件的命名遵循<原子数据集>_<热定标方案>_KN_<镧系元素占比>X_lan_<特征速度>v_<质量>M_1D_spec.h5格式，各字段含义如下： atomic dataset（原子数据集）可选值为：HULLAC、ATOMIC或Autostructure； thermalization prescription（热定标方案）可选值为：局域（local）或全域（global）； lanthanide fraction（镧系元素占比）：抛射物中镧系元素的质量占比； characteristic velocity（特征速度）：抛射物的运动速度，以光速为单位； mass（抛射物质量）：抛射物的质量，以太阳质量为单位。
