From a principal component analysis (PCA) of 78 z~3 high-quality quasar spectra in the SDSS-DR7 we derive the principal components that characterize the QSO continuum over the...
我们基于斯隆数字巡天第七数据发布版(SDSS-DR7)中78个红移z≈3的高质量类星体光谱开展主成分分析(Principal Component Analysis,PCA),由此提取出了能够表征类星体(Quasi-Stellar Object,QSO)连续谱特征的主成分……
