OBSERVATIONS OF A COMPLETE SAMPLE OF H-ALPHA EMISSION-LINE GALAXIES -LONG-SLIT SPECTROSCOPY OF GALAXIES IN UCM LIST-1 AND LIST-2

Spectroscopic observations for the full sample of Her emission-line ga laxy candidates (ELGs) from the Universidad Complutense de Madrid obje ctive-prism survey Lists 1 and 2 have been obtained in order to invest igate fully the properties of the survey constituents as well as the s election characteristics and completeness limits of the survey itself. The spectroscopic data include redshifts, line fluxes, equivalent wid ths, emission-line ratios, optical reddening estimates and synthesized color indexes. We find that 74% of the objects in this sample do exhi bit emission Lines. We compare our observational data, with parameters given in the published survey lists in order to assess the usefulness of the latter. The different emission-line galaxies have been classif ied according to their spectra in several groups. Gray-scale images of the CCD spectra near the main emission lines, spatial profiles at the continuum and the Line for [OIII] lambda 5007 and H alpha lines, as w ell as plots of the coadded spectra of selected galaxies are presented , and a number of peculiar objects are described.
