WINGS equivalent widths

Emission lines have negative EWs, and absorption lines positive EWs, with all the quantities given at rest frame. Spectra were obtained with WYFFOS@WHT and 2dF@AAT and have a resolution of 6 and 9 AA FWHM, respectively.

The wavelength coverage ranges from ∼ 3590 to ∼ 6800 AA for the WHT observations, while spectra taken at the AAT cover the ∼ 3600 to ∼ 8000 AA domain. For each object the catalog gives also the magnitude and radial completeness (or weight) that, once combined, describe the global completeness of the sample. Finally a spectral classification is available, made on the basis of the presence/absence and intensity of spectral lines (following Poggianti et al., 1999): 1=e(a); 2=e(b); 3=e(c); 4=k; 5=k+a; 6=a+k.
