Modeling Data from "The VLA/ALMA Nascent Disk and Multiplicity (VANDAM) Survey of Orion Protostars. Insights from Radiative Transfer Modeling"

This dataset includes the results from the radiative transfer modeling done in the paper "The VLA/ALMA Nascent Disk and Multiplicity (VANDAM) Survey of Orion Protostars: Insights from Radiative Transfer Modeling" by Sheehan et al. Included are the full posteriors from the model fitting for each source as a Python pickle file that contains a dictionary with keys given by the source names, e.g. "HOPS-2", that point to numpy arrays containing the posterior distributions. The information can be loaded like so: <pre><code class="language-python">import pickle data, keys = pickle.load(open("posteriors.p","rb"))</code></pre> Here "keys" is a list containing the names of the parameters from the model fit that are a part of the posterior distribution for each source. Also included are the configuration files and datasets used in the modeling for each source, as well as the results from the fit so that anyone can work with these models for their own purposes. An example script that shows how to use these files is included, and further information can be found at http://pdspy.readthedocs.io.本数据集收录了Sheehan等人发表于论文《猎户座原恒星的VLA/ALMA初生盘与多重性（VANDAM）巡天：来自辐射传输建模（radiative transfer modeling）的启示》中的辐射传输建模结果。数据集包含所有源的模型拟合完整后验分布，存储为Python pickle格式文件，该文件为字典结构，键名为源名称（例如“HOPS-2”），对应的值为存储后验分布的numpy数组。其加载方式如下：<pre><code class="language-python">import pickle data, keys = pickle.load(open("posteriors.p","rb"))</code></pre> 其中“keys”为列表，包含每个源后验分布所涉及的模型拟合参数名称。此外，数据集还包含各源建模所用的配置文件与数据集，以及拟合结果，以供任意使用者基于这些模型开展自主研究。附带一份展示如何使用这些文件的示例脚本，更多详细信息可访问 http://pdspy.readthedocs.io。
