论文摘要
在Herschel光谱和光度成像接收器（SPIRE）傅立叶变换光谱仪（FTS）仪表团队中开发的Spire FTS光谱特征发现器（FF）是一个自动光谱拟合程序，该频谱特征拟合程序试图在Spire FTS光谱中找到重要的特征。 $^3 $ p $ _1 $ - $^3 $ p $ _0 $和$^3 $ p $ _2 $ - $^3 $ p $ _1 $中性碳精细结构线是碳富含碳的远红外天体物理学来源的常见功能。这些功能由于其通常较低的振幅和线条混合而很难使用自动特征检测程序进行检测。在本文中，我们描述和验证了旨在检测尖峰光谱数据中观察到的中性碳发射的FF子规范。
The SPIRE FTS Spectral Feature Finder (FF), developed within the Herschel Spectral and Photometric Imaging Receiver (SPIRE) Fourier Transform Spectrometer (FTS) instrument team, is an automated spectral feature fitting routine that attempts to find significant features in SPIRE FTS spectra. The $^3$P$_1$ - $^3$P$_0$ and $^3$P$_2$ - $^3$P$_1$ neutral carbon fine structure lines are common features in carbon rich far-infrared astrophysical sources. These features can be difficult to detect using an automated feature detection routine due to their typically low amplitude and line blending. In this paper we describe and validate the FF sub-routine designed to detect the neutral carbon emission observed in SPIRE spectral data.
