This first public data release contains FITS files with 2dF spectra and Digitized Sky Survey images of each galaxy, together with a host of other information, such as the galaxies' positions, luminosities, redshifts, and spectral types.
The data are also available in ASCII tables and, for Linux users, in the form of an mSQL database that allows sophisticated searching and matching facilities.
This release also contains:
Programs for accessing the FITS files
Descriptions of the input catalogues, the observations, and spectroscopic data
Details of how the survey mask, selection function, and completeness are determined
Programs to compute these masks
Image and spectrum display programs
The data from October 1997 through January 2000 of the 2dF Galaxy Redshift Survey, including redshifts, spectra and photometry for approximately 100,000 galaxies, will soon be released on a set of CD-ROMs. The CD-ROMs contain the survey catalogues, FITS files for each galaxy, an mSQL database that can be run under RedHat Linux 6.2, and papers, graphs, tables, documentation and other software related to the survey. The FITS files for each galaxy contain photometric information, a finding chart, object spectrum, sky spectrum, and variance array. The mSQL database indexes all the data in the FITS files and can be used to display the finding chart and spectrum of individual galaxies, and to perform SQL queries on the data.
