News:
18/11/04 - IMPORTANT: The fluxes in previous versions
of the catalogue were low by a factor (1+z). Please download the
new catalogue.
03/11/04 - [O I]6300 has been added to the catalogue
18/10/04 - The equivalent widths were missing and have been included
13/09/04 - [S II]6731 has been added to the
emission line catalogue
10/10/05 - [O III]4363,4959 have been added to the
emission line catalogue
This catalogue contains a table of measured emission line fluxes used in our work (see Tremonti et al (2004) for details on our pipeline). We have measured all spectroscopic targets in the SDSS DR2 whose SPECTROTYPE is GALAXY. The resulting catalogue contains 261054 objects. Notice that this number includes duplicate observations!
General notice: Please note that our line fluxes are corrected for foreground (galactic) reddening using the O'Donnell, J.E., 1994, ApJ, 422, 158. If you have any questions about this please feel free to contact us.

| H_ALPHA_EQW & H_ALPHA_EQW_ERR | Equivalent width of the Halpha line its associated error |
| <XXX>_EQW & <XXX>_EQW_ERR | Equivalent width of line XXX and its error where XXX is H_BETA, OIII_5007, OII_3726 (despite the name this is the equivalent width for the 3727 doublet), NII_6584, SII_6717, SII_6731, OI_6300 |
All the fluxes are given in the units of 10^(-17) erg/s/cm^2 and the equivalent widths in Ångström with emission lines having negative equivalent widths.
