VizieR Online Data Catalog: Principal Component Analysis of QSO UV spectra (Paris+, 2011)
Abstract
The first 10 Principal Components derived from a sub-sample of SDSS-DR7 QSO spectra are presented over the 1020-2000A wavelength range (in the restframe, xi.dat) and redwards to the Ly-alpha emission (1216-2000A in the restframe, zeta.dat).
A projection matrix is also provided (proj.dat), allowing to fit a quasar continuum. (3 data files).- Publication:
