A Modular Set Of Synthetic Spectral Energy Distributions For Young Stellar Objects - Robitaille (2017) - V1.1 [Hyperion Files]

These are the input and output files for the radiative transfer code (Hyperion) for the model sets presented in <em>A modular set of synthetic spectral energy distributions for young stellar objects</em>, Robitaille (2017) Each model set is provided as a single tar file. Each tar file expands to <strong>grids-1.1/&lt;set name&gt;</strong>, so if you expand all tar files in the same folder, you will end up with a single <strong>grids-1.1</strong> folder with 18 sub-folders, one for each model set. For a given model set, the files are as follows: grids-1.1/&lt;set name&gt;/input - input Hyperion files grids-1.1/&lt;set name&gt;/log - log files from Hyperion grids-1.1/&lt;set name&gt;/output - output Hyperion files grids-1.1/&lt;set name&gt;/par - parameters for each model grids-1.1/&lt;set name&gt;/ranges.conf - ranges of parameters varied in the model set grids-1.1/&lt;set name&gt;/parameters.hdf5 - table of parameters for all models grids-1.1/&lt;set name&gt;/d03_5.5_3.0_A_sub.hdf5 - dust file used for the models Given the large number of models for some of the model sets, the models are not all stored directly inside the par, input, output or log directories - instead these directories contain folders formed from the first two characters (forced to lowercase) of the names of the models they contain. For example, a3 contains all models whose name starts with a3 or A3. This was done to avoid having too many files in a single folder which can cause issues on certain file systems. For the Hyperion input and output files, in some cases an _sed file is present. In these cases, the output SEDs (and polarization spectra) should be read from the _sed file, not the original output file. This is the case for all models that are in a set for which the ambient medium was present, as described in §4.2.3 of Robitaille (2017). Furthermore, in some cases the SED file is called _sed_noscat to indicate that scattering was not included, as described in §5.1 of Robitaille (2017). To avoid taking up too much disk space, the Hyperion HDF5 input/output files use external links to refer to each other and to the dust file. To make sure the links work, you should do all operations with the input/output files from the directory containing <strong>grids-1.1</strong>. For example, to open a Hyperion output file, you would need to do (in Python): In [1]: from hyperion.model import ModelOutput In [2]: mo = ModelOutput('grids-1.1/s---s-i/output/a3/A3kQmQtj.rtout') A notebook with examples of reading in the output files can be found here: https://github.com/hyperion-rt/paper-2017-sed-models/blob/master/notebook_raw/reading_raw_files.ipynb More information on using Hyperion, including reading input/output files, can also be found at http://docs.hyperion-rt.org For <strong>announcements</strong> of new versions of these models, you can subscribe to the following mailing list: https://groups.google.com/forum/#!forum/protostars For <strong>questions or issues</strong> using these models, you can open a GitHub issue in the companion repository: https://github.com/hyperion-rt/paper-2017-sed-models/issues/new本数据集为发表于《年轻恒星天体模块化合成光谱能量分布集》（Robitaille，2017）中的模型集合所配套的辐射传输代码（Hyperion）输入输出文件。每个模型集合均以单个tar归档文件形式提供。解压任意tar归档文件后，将得到`grids-1.1/<集合名称>`目录结构；若将所有tar归档文件解压至同一目录，则最终将得到一个包含18个子目录的总`grids-1.1`文件夹，每个子目录对应一个模型集合。 针对单个模型集合，其内部文件结构如下： - `grids-1.1/<集合名称>/input`：Hyperion输入文件 - `grids-1.1/<集合名称>/log`：Hyperion运行日志文件 - `grids-1.1/<集合名称>/output`：Hyperion输出文件 - `grids-1.1/<集合名称>/par`：各模型的参数文件 - `grids-1.1/<集合名称>/ranges.conf`：本模型集合中待调整参数的取值范围配置文件 - `grids-1.1/<集合名称>/parameters.hdf5`：所有模型的参数表文件 - `grids-1.1/<集合名称>/d03_5.5_3.0_A_sub.hdf5`：本模型所用的尘埃文件 由于部分模型集合包含大量模型，因此par、input、output及log目录并未直接存储所有模型文件，而是将模型按名称的前两个字符（统一转为小写）分组为子目录。例如，`a3`子目录将存储所有名称以`a3`或`A3`开头的模型。此举旨在避免单个文件夹内文件数量过多，防止在部分文件系统中引发异常。 针对Hyperion的输入输出文件，部分场景下会存在后缀为`_sed`的文件。在此类场景中，需从`_sed`文件中读取输出的光谱能量分布（SED）与偏振光谱，而非原始输出文件。此类情况适用于所有包含环境介质的模型集合，具体说明详见Robitaille（2017）的§4.2.3。此外，部分场景下的SED文件会被命名为`_sed_noscat`，用以表示该文件未包含散射效应相关计算，具体说明详见Robitaille（2017）的§5.1。 为节省磁盘空间，Hyperion的HDF5格式输入输出文件采用外部链接实现文件间及与尘埃文件的相互引用。为确保链接正常生效，请始终在包含`grids-1.1`的根目录下执行相关操作。例如，若需读取Hyperion输出文件，可在Python中执行如下代码： python In [1]: from hyperion.model import ModelOutput In [2]: mo = ModelOutput('grids-1.1/s---s-i/output/a3/A3kQmQtj.rtout') 本数据集附带了读取输出文件的示例Jupyter Notebook，可通过以下链接获取： https://github.com/hyperion-rt/paper-2017-sed-models/blob/master/notebook_raw/reading_raw_files.ipynb 有关Hyperion的更多使用说明（包括输入输出文件读取方法），可访问以下官方文档： http://docs.hyperion-rt.org 若需获取本模型集合新版本的发布公告，可订阅以下邮件列表： https://groups.google.com/forum/#!forum/protostars 若在使用本模型集合过程中遇到问题或发现异常，可在配套GitHub仓库提交Issue： https://github.com/hyperion-rt/paper-2017-sed-models/issues/new
