低分辨率光谱中二级污染的校正

Correcting second-order contamination in low-resolution spectra

V. Stanishev

摘要:

本文提出了一种校正低分辨率天文光谱二级污染的经验方法。该方法被开发用于校正在北欧光学望远镜的ALFOSC摄谱仪的棱镜#4获得的光谱,并在附近两个明亮的Ia型超新星的光谱上证明了该方法的性能。

英文摘要:

An empirical method for correcting low-resolution astronomical spectra for second-order contamination is presented. The method was developed for correcting spectra obtained with grism #4 of the ALFOSC spectrograph at the Nordic Optical Telescope and the performance is demonstrated on spectra of two nearby bright Type Ia supernovae.
