Data from: ProSpect: generating spectral energy distributions with complex star formation and metallicity histories

We introduce ProSpect, a generative galaxy spectral energy distribution (SED) package that encapsulates the best practices for SED methodologies in a number of astrophysical domains. ProSpect comes with two popular families of stellar population libraries (BC03 and EMILES), and a large variety of methods to construct star formation and metallicity histories. It models dust through the use of a Charlot & Fall attenuation model, with re-emission using Dale far-infrared templates. It also has the ability to model active galactic nucleus (AGN) through the inclusion of a simple AGN and hot torus model. Finally, it makes use of MAPPINGS-III photoionization tables to produce line emission features. We test the generative and inversion utility of ProSpect through application to the Shark galaxy formation semi-analytic code, and informed by these results produce fits to the final ultraviolet to far-infrared photometric catalogues produces by the Galaxy and Mass Assembly Survey. As part of the testing of ProSpect, we also produce a range of simple photometric stellar mass approximations covering a range of filters for both observed frame and rest-frame photometry.

我们介绍ProSpect——一款生成式星系光谱能量分布（SED）软件包，它整合了多个天体物理领域中SED方法学的最佳实践。ProSpect内置了两大主流恒星族群库（BC03与EMILES），并提供多种构建恒星形成及金属丰度历史的方法。该软件包采用Charlot & Fall消光模型对尘埃进行建模，并通过Dale远红外模板模拟尘埃再辐射过程。此外，它可通过集成简易AGN及热环模型对活动星系核（AGN）进行建模。最后，它利用MAPPINGS-III光电离表生成线发射特征。我们通过将ProSpect应用于Shark星系形成半解析代码，测试了其生成与反演功能；基于这些结果，我们对星系与质量汇聚巡天（Galaxy and Mass Assembly Survey）产出的紫外至远红外最终测光目录进行了拟合。作为ProSpect测试的一部分，我们还生成了一系列简易测光恒星质量近似值，覆盖观测帧与静止帧测光的多种滤光片。
