Spitzer Mid-Infrared Star Formation Indicators (MIR_SFR)

The Mid-Infrared Star Formation Indicators (MIR_SFR) set is a collection of continuous, monochromatic star formation rate (SFR) indicators over the mid-infrared wavelength range of 6 - 70 microns. They were derived from a sample of 58 star forming galaxies (SFGs) in the Spitzer-SDSS-GALEX Spectroscopic Survey (SSGSS) at z < 0.2, which contains a rich suite of multi-wavelength photometry and spectroscopy ranging from ultraviolet to infrared light. The data from the Spitzer infrared spectrograph (IRS) of these galaxies, which spans 5 - 40 microns, is anchored to their photometric counterparts. The spectral region between 40 - 70 microns is interpolated using dust model fits to the IRS spectrum and Spitzer 70 and 160 micron photometry.

This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.

中红外恒星形成率指标（Mid-Infrared Star Formation Indicators, MIR_SFR）数据集是一组覆盖6至70微米中红外波段的连续单色恒星形成率（Star Formation Rate, SFR）指标。其数据源自红移z<0.2的斯皮策-斯隆数字巡天-星系演化探测器光谱巡天（Spitzer-SDSS-GALEX Spectroscopic Survey, SSGSS）中的58个恒星形成星系（Star Forming Galaxies, SFGs）样本；该巡天项目拥有从紫外到红外的丰富多波段测光与光谱数据集合。这些星系的斯皮策红外光谱仪（Infrared Spectrograph, IRS）数据覆盖5至40微米波段，且已与对应的测光数据完成锚定匹配。40至70微米波段的光谱区域则通过尘埃模型拟合IRS光谱与斯皮策70、160微米测光数据进行插值补全。

本数据集及相关服务由IPAC下属的红外科学档案馆（Infrared Science Archive, IRSA）提供，该机构由加州理工学院依据与美国国家航空航天局签订的合同进行运营管理。
