Abstract:
We study the two-point correlation function of a uniformly selected
sample of 4426 luminous optical quasars with redshift 2.9≤z≤5.4
selected over 4041deg2 from the Fifth Data Release of the Sloan
Digital Sky Survey. We fit a power-law to the projected correlation
function wp(rp) to marginalize over redshift-space distortions and
redshift errors.

Note (1): Objects identified as [SSO2007] DDD.dddddd+DD.dddddd in Simbad.
Note (2): Re-measured using line fitting procedures.
Note (3): Corrected for Galactic extinction (Schlegel et al.,
1998ApJ...500..525S 1998ApJ...500..525S); they use the ubercalibration described by
Padmanabhan et al. (2007MNRAS.378..852P 2007MNRAS.378..852P), which differs slightly
from that used in the official DR5 quasar catalog (Schneider et
al., 2007AJ....134..102S 2007AJ....134..102S).
Note (4): The subsample clustering analysis is 1) Selected from the Main
SDSS survey with main target selection criteria 2) With target version
v310 or later.
