Absorption spectrum of the QSO PKS2126-158
Listed in IVOA Registry (Virtual Observatory)
Spectra of the z_em_=3.268 quasar PKS 2126-158 have been obtained in the wavelength range 430-662nm with a resolution R=27000 and an average signal to noise ratio s/n=25 per resolution element. 12 metal absorption systems have been identified, two of which were previously unknown.
Description
All the lines shortward of the Lyman{alpha} emission not identified as due to metals have been fitted as Lyman{alpha} and Lyman{beta}. We reported statistical analysis of this sample of lines.
In particular, the two-point correlation function for metal systems has been computed.
