SPADES：恒星参数测定软件
SPADES: a Stellar PArameters DEtermination Software
摘要：
随着大量的光谱数据的可用今天和非常大的调查（如盖亚），需要自动数据分析软件是毫无疑问的。因此，我们开发了一个自动光谱分析程序，用于确定恒星参数：径向速度，有效温度，表面重力，微湍流，金属丰度和元素丰度的元素存在于光谱范围内。本软件的目标星应包括所有类型的星。分析方法依赖于对目标恒星的光谱与合成光谱库进行逐线比较。这个想法是建立在开发TGMET（Katz等人，1998年和Soubiran等人，2003年）ETOILE（Katz 2001年）和Abbo（Bonifacio和Caffau 2003年）软件的经验基础上的。该方法被提出，并与GIRAFFE模拟光谱的性能示出与高分辨率（R = 25000），与高和低信噪比（下至SNR= 30）。这些光谱应该接近Gaia-ESO调查（GCDS）的目标。
英文摘要：
With the large amounts of spectroscopic data available today and the very large surveys to come (e.g. Gaia), the need for automatic data analysis software is unquestionable. We thus developed an automatic spectra analysis program for the determination of stellar parameters: radial velocity, effective temperature, surface gravity, micro-turbulence, metallicity and the elemental abundances of the elements present in the spectral range. Target stars for this software should include all types of stars. The analysis method relies on a line by line comparison of the spectrum of a target star to a library of synthetic spectra. The idea is built on the experience acquired in developing the TGMET (Katz et al. 1998 and Soubiran et al. 2003) ETOILE (Katz 2001) and Abbo (Bonifacio & Caffau 2003) softwares. The method is presented and the performances are illustrated with GIRAFFE-like simulated spectra with high resolution (R = 25000), with high and low signal to noise ratios (down to SNR= 30). These spectra should be close to what could be targeted by the Gaia-ESO Survey (GCDS).
