A quasar sample for the Lyα forest studies from the Data Release 10 of the Sloan Digital Sky Survey
We present a new sample of the z ≥ 2 quasar spectra. It contains 102 643 spectra which were visually selected from the SDSS DR10, and includes also a subsample of 65 976 spectra for the composite spectra compilation. This sample will be used for the Lyα forest studies, and can be used for other stud...
