Abstract:
We present a catalogue of 2135 galaxy redshifts from the VLT LBG
Redshift Survey (VLRS), a spectroscopic survey of z∼3 galaxies in wide
fields centred on background quasi-stellar objects. We have used deep
optical imaging to select galaxies via the Lyman-break technique.
Spectroscopy of the Lyman-break galaxies (LBGs) was then made using
the Very Large Telescope (VLT) Visible Multi-Object Spectrograph
(VIMOS) instrument, giving a mean redshift of z=2.79. We
analyse the clustering properties of the VLRS sample and also of the
VLRS sample combined with the smaller area Keck-based survey of
Steidel et al. (2003, Cat. J/ApJ/592/728).
Description:
These tables contain the QSO and galaxy redshift data obtained using
the VLT VIMOS instrument and presented within the VLRS I (Bielby et
al. 2011MNRAS.414....2B 2011MNRAS.414....2B) and VLRS III (Bielby et al.,
2013MNRAS.430..425B 2013MNRAS.430..425B) papers.
The data were observed as part of ESO proposals: 075.A-0683,
077.A-0612 and 079.A-0442. The accuracy on the redshift measurements
is ∼300km/s.

U-B (Vega) colour if SYS = 1 or SYS = 2
u-g (AB) colour if SYS = 3
Note (2): Colour index 2 as follows:
B-R (Vega) colour if SYS = 1
B-V (Vega) colour if SYS = 2
g-r (AB) colour if SYS = 3
Note (3): Reference magnitude as follows:
R (Vega) magnitude if SYS = 1
V (Vega) magnitude if SYS = 2
r (AB) magnitude if SYS = 3
Note (4): System used as follows:
1 = U-B in col1, B-R in col2, R in mag
2 = U-B in col1, B-V in col2, V in mag
3 = u-g in col1, g-r in col2, r in mag
Note (5): Confidence flag as described in the paper. Takes values from 0.5-1.0,
where Q=1.0 is highest confidence value.
