2dF Galaxy Redshift Survey
(2dFGRS)
(imaging survey of 300,000 extragalactic objects)
The 2dF Galaxy Redshift Survey
was a 1500-square-degree extragalactic
survey covering survey fields
around the galactic north and south poles
(providing a good view beyond the Milky Way).
It was carried out with the 3.9-m Anglo-Australian Telescope (AAT) between 1997 and 2002.
Photometer data for 380,000 objects
(galaxies, quasars) was collected along with
spectroscopic data for 245,000 of them
using the telescope's the 2dF multi-object spectrograph.
The limiting magnitude was +19.5
covering redshifts to 0.3.
