Spectroscopy of KISS Emission-Line Galaxy Candidates. IV. KPNO and WIYN Observations
Abstract
Spectroscopic observations for 614 emission-line galaxy (ELG) candidates from the KPNO International Spectroscopic Survey (KISS) have been obtained using the KPNO 2.1 m telescope and the WIYN 3.5 m telescope. KISS is a wide-field objective-prism survey for extragalactic emission-line objects that has cataloged over 2400 ELG candidates to date. Spectroscopic follow-up observations are being carried out at several telescopes to study the characteristics of the survey objects. We present the following data derived from the KPNO spectra: redshifts, reddening estimates, line equivalent widths, Hα line fluxes, and emission-line ratios. The galaxies have been classified based on their emission-line characteristics. The procedure for selecting the ELG candidates in KISS is found to be very reliable: the follow-up observations verify the presence of emission lines in 93% of the sample presented here. A comparison of objective-prism survey data-redshifts, Hα line fluxes, and equivalent widths-to the long-slit measurements shows good overall agreement.
