论文摘要
必须从牙槽污染中纠正地面的红外光谱观察结果,以使其准备进行科学分析。但是,矫正通常是一个繁琐的过程,需要大量的专业知识才能在合理的时间范围内产生准确的结果。为了解决这些不便,我们提出了一种新的矫正方法,该方法采用了对Vega类似物的大致同时观察来测量大气传播。连续重建和光谱拟合后,从观察到的VEGA型光谱中删除了出色的特征,结果用于取消科学光谱上的矫流吸收特征。此方法是作为电丝(来自Alicante的Telluric校正)实现的,这是一种基于Python的Web应用程序,具有用户友好的界面,其Beta版本将很快发布。
Infrared spectroscopic observations from the ground must be corrected from telluric contamination to make them ready for scientific analyses. However, telluric correction is often a tedious process that requires significant expertise to yield accurate results in a reasonable time frame. To solve these inconveniences, we present a new method for telluric correction that employs a roughly simultaneous observation of a Vega analog to measure atmospheric transmission. After continuum reconstruction and spectral fitting, the stellar features are removed from the observed Vega-type spectrum and the result is used for cancelling telluric absorption features on science spectra. This method is implemented as TelCorAl (Telluric Correction from Alicante), a Python-based web application with a user-friendly interface, whose beta version will be released soon.
