CIV absorption catalog in SDSS DR12

For each sight-line, identified by Column 1 and 2, we report the absorber’s redshift (Column 3), column density in log(cm −2 ) (Column 4), Doppler velocity dispersion in km s −1 (Column 5), rest equivalent width for 1548 Å W𝑟 ,1548 (Column 6), rest equivalent width for 1550 Å W𝑟 ,1550 (Column 7), the posterior probability of the C iv absorber P(M𝐷 ) (Column 8), and the posterior probability of the singlet absorber P(M𝑆 ) (Column 9). We show only absorbers with P(M𝐷 )≠NaN. This table demonstrates a portion of the full table for the first ten rows. Note that those measurements with large errors are uncertain (i.e. low absorption model posterior probability).
