Parameter estimation data release for paper "Waveform systematics in identifying gravitationally lensed gravitational waves: Posterior overlap method"
收藏资源简介:
This is a second data release for the paper "Waveform systematics in identifying gravitationally lensed gravitational waves: Posterior overlap method", which is available on https://arxiv.org/abs/2306.12908. This data release contains posterior samples and configuration files for parameter estimation runs performed for the paper. For the lensing hypothesis tests results see the other data release for the same paper. For each event that we have run parameter estimation for, we provide a tar.gz file that includes the configurations, the priors and the results for each run, typically with several different waveforms. All runs were performed with parallel bilby with different versions as described in section 6.1 of the paper. The input data is available from GWOSC. The results for IMRPhenom* waveforms (runs with parallel bilby version 1.0.1) are in json format, while for SEOBNRv5PHM and NRSur7dq4 (run with parallel bilby version 2.0.2) some of the results are in hdf5 and others in json, depending on whether multiple runs were merged together. These should be readable with bilby or pesummary. We provide the "complete" configuration files processed by bilby. These can be used for reproducing the runs, but the prior file information needs to be added with a syntax like the following `prior-file=ProdF4.prior`. Generally most runs use the same prior file, with the labels `Prod*.prior`, taken from the LVK analyses. The priors used for the aligned-spin waveforms have the label `_AS`. For the NRSur7dq4 waveform we use a restricted prior with the label `_NR_Sur_constrMtot`. For GW190527 we also use a different prior for IMRPhenomXP and IMRPhenomTPHM, which has the label `_restricted`. Also note that for the result file GW190527_NRSur7dq4_N4096_nact50_fmin0_nparallel3_merged_result.hdf5 this was merged from the results obtained with the config GW190527_NRSur7dq4_N4096_nact50_fmin0_nparallel3_config_complete.ini together with the fourth chain of identical configuration.
本数据集为论文《引力透镜引力波识别中的波形系统误差:后验重叠法》的第二版数据发布,该论文可在https://arxiv.org/abs/2306.12908获取。本次数据发布包含为该论文开展的参数估计运行所需的后验样本与配置文件。关于透镜假设检验的结果,请参阅该论文的另一项数据发布。 对于每一项完成参数估计的引力波事件,我们提供了tar.gz格式压缩包,其中包含各次运行的配置文件、先验信息与结果——通常针对多种不同的波形模型开展了多组运行。所有运行均采用论文6.1节所述的不同版本的并行bilby (parallel bilby)完成。 输入数据可从引力波开放科学中心(GWOSC)获取。IMRPhenom*系列波形(采用并行bilby 1.0.1版本运行)的结果以json格式存储;而SEOBNRv5PHM与NRSur7dq4波形(采用并行bilby 2.0.2版本运行)的结果部分存储为hdf5格式,部分为json格式,这取决于是否合并了多次运行的结果。上述结果均可通过bilby或pesummary读取。 我们提供了经bilby处理后的"完整"配置文件,可用于复现运行流程,但需补充先验文件信息,补充语法格式如下:`prior-file=ProdF4.prior`。多数运行采用统一的先验文件,其标签为`Prod*.prior`,该先验文件源自LIGO科学合作组、Virgo合作组与KAGRA合作组(LVK)的分析工作。用于对齐自旋波形的先验带有标签`_AS`。针对NRSur7dq4波形,我们使用了带有`_NR_Sur_constrMtot`标签的受限先验。对于GW190527事件,我们还为IMRPhenomXP与IMRPhenomTPHM波形使用了带有`_restricted`标签的差异化先验。 此外请注意,结果文件`GW190527_NRSur7dq4_N4096_nact50_fmin0_nparallel3_merged_result.hdf5`是由配置文件`GW190527_NRSur7dq4_N4096_nact50_fmin0_nparallel3_config_complete.ini`对应的运行结果,与该配置的第四条链合并得到的。
