摘要:

SPIRE FTS光谱特征拟合程序(FF)由赫歇尔光谱和光度成像接收器(SPIRE)傅立叶变换光谱仪(FTS)仪器团队开发,是一种自动化光谱特征拟合程序,试图在SPIRE FTS光谱中找到重要特征。$^3$ P $_1$ - $^3$ P $_0$和$^3$ P $_2$ - $^3$ P $_1$中性碳精细结构线是富碳远红外天体物理源的共同特征。这些特征可能难以使用自动特征检测例程来检测,这是由于它们通常是低幅度和线混合。在本文中,我们描述和验证FF子例程设计检测中性碳排放SPIRE光谱数据中观察到的。

英文摘要:

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.
