Spectroscopy of KISS Emission-Line Galaxy Candidates. III. A Second Set of MDM Observations
Abstract
Spectroscopic observations for 315 emission-line galaxy (ELG) candidates from the KPNO International Spectroscopic Survey (KISS) have been obtained using the MDM Observatory 2.4 m telescope on Kitt Peak. KISS is a wide-field objective-prism survey for extragalactic emission-line objects that has cataloged over 2200 ELG candidates to date. Spectroscopic follow-up observations are being carried out to study the characteristics of the survey objects. The observational data presented here include 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: 93% of the candidates in this sample are verified to have emission lines. A comparison of objective-prism survey data-redshifts, Hα line fluxes, and equivalent widths-to the long-slit measurements shows good overall agreement.
