| 1 | Relative flux calibration for the Guoshoujing Telescope (LAMOST)显示文摘This paper presents a relative flux calibration method for the Guoshoujing Telescope (LAMOST), which may be applied to connect a blue spectrum to a red spectrum to build the whole spectrum across the total wavelength range (3700 ~ 9000 A). In each spectrograph, we estimate the effective temperatures of selected stars using a grid of spectral line indices in the blue spectral range and a comparison with stellar atmosphere models. For each spectrograph, stars of types A and F are selected as pseudo-standard stars, and the theoretical spectra are used to calibrate both the blue (3700 ~ 5900 A) and red spectrograph arms (5700 ~ 9000 A). Then the spectral response function for these pseudo-standard stars could be used to correct the raw spectra provided by the other fibers of the spectrograph, after a fiber efficiency function has been derived from twilight flat-field exposures. A key problem in this method is the fitting of a pseudo stellar continuum, so we also give a detailed description of this step. The method is tested by comparing a small sample of LAMOST spectra calibrated in this way on stars also observed by the Sloan Digital Sky Survey. The result shows that the T eff estimation and relative flux calibration method are adequate. | Yi-Han Song A-Li Luo Georges Comte Zhong-Rui Bai Jian-Nan Zhang Wei Du Hao-Tong Zhang Jian-Jun Chen Fang Zuo Yong-Heng Zhao | 2012 | Research in Astronomy and Astrophysics2012，12，4： | 4 |
| 2 | LAMOST类星体[OIII]线附近天光背景扣除显示文摘扣除天光背景的好坏是影响谱线信噪比很重要的因素,同时由于天光光纤数量有限以及光谱仪漂移等多方面因素的影响导致减天光是光纤光谱数据处理中公认的难点。目前已有的减天光方法主要是针对全谱的天光成分扣除,没有关注在特殊谱线位置上的局部天光情况,尤其是低红移类星体非常重要的[OIII]线附近的天光背景。探索了一种局部精细的天光背景扣除方法,解决了类星体中Hβ-[OIII]的宽线经常受到减天光精度干扰的问题。利用LAMOST减天光前的原始流量以及相对流量改正数据,根据同一观测天区的超级天光光谱对背景进行扣除。实验结果表明,在不同红移类星体中,该方法减天光后Hβ-[OIII]区间的光谱质量相对于原始LAMOST光谱批处理程序都有了明显的提高,这更有利于后续的谱线分析,同时为少部分LAMOST光谱批处理程序没处理好的特殊光谱提供了补充的解决方法。该方法目前已应用于搜寻双峰活动星系核候选体的预处理中。 | 石志鑫 Georges Comte 罗阿理 屠良平 赵永恒 吴福朝 | 2014 | 光谱学与光谱分析2014，34，11： | 3 |
