3.4 micron Background MCMC Posterior Chains

Extragalactic background light (EBL) at 3.4 microns from galaxies as predicted using the mean spectral energy distribution (SED) of galaxies measured in Lake and Wright (2016, DOI: 10.21105/astro.1603.0729) and the luminosity function (LF) Markov chain Monte Carlo (MCMC) posterior chains from Lake et al. (2018b). The LF posterior chains are available from Figshare under DOI: 10.6084/m9.figshare.4109625 . The first two columns are indices that match the LF posterior chains. The third column is the background from galaxies at redshifts closer than z=1 and the fourth column is the prediction from the same parameters closer than z=5, all in kilo-Janskies per steradian. The files are gzipped ( http://www.gzip.org/ ) IPAC tables ( http://irsa.ipac.caltech.edu/applications/DDGEN/Doc/ipac_tbl.html ). A full description of how these files were produced is in Lake et al. (2019, in preparation).<br>

本数据集为基于莱克与赖特（Lake and Wright, 2016, DOI: 10.21105/astro.1603.0729）中测得的星系平均光谱能量分布（spectral energy distribution, SED），以及莱克等人（Lake et al., 2018b）给出的光度函数（luminosity function, LF）马尔可夫链蒙特卡洛（Markov chain Monte Carlo, MCMC）后验链，所预测得到的3.4微米波段星系河外背景光（Extragalactic background light, EBL）。该光度函数后验链可于Figshare平台获取，对应的DOI为10.6084/m9.figshare.4109625。数据文件的前两列为与光度函数后验链相匹配的索引；第三列为红移z<1的星系贡献的背景光强度，第四列为使用相同参数对红移z<5的星系背景光的预测结果，所有数值的单位均为千央斯基每球面度（kilo-Janskies per steradian）。本数据集采用gzip压缩格式的IPAC表格存储，相关格式说明可参考http://www.gzip.org/ 与http://irsa.ipac.caltech.edu/applications/DDGEN/Doc/ipac_tbl.html。关于这些文件生成方式的完整详细说明详见莱克等人（Lake et al., 2019, 待刊）。
