We present preliminary results from our second H\alpha-selected survey list of emission-line galaxy candidates from the KPNO International Spectroscopic Survey (KISS) project. KISS is a wide-field survey for extragalactic emission-line objects being carried out with the Burrell Schmidt at Kitt Peak. It combines the classical objective-prism technique for finding strong-lined star-forming galaxies and AGNs with the use of CCD detectors and automated reduction software to enhance and streamline the survey process. Because KISS has good depth plus significant areal coverage, it is a powerful tool for the study of activity in galaxies. Our new survey strip covers 66 square degrees across the North Galactic Cap at a declination of 43 degrees. This location was chosen so that our survey strip runs through the heart of the Boötes Void. The data consist of deep (to B = 20) objective-prism images and direct images in both B and V. The objective-prism data cover the spectral region from 6400 to 7200 Å, which includes the H\alpha line for objects with redshift less than ~0.1.
A total of 1031 emission-line galaxy candidates are cataloged in this new list (15.6 per deg2). Our direct images provide accurate photometry for all candidates, while rough redshifts and line strengths can be measured from the objective-prism spectra. We describe the overall characteristics of the survey constituents, presenting distributions of magnitude, color, redshift, and emission-line strength and comparing these with results from our previous lists as well as with other surveys. We also take a preliminary look at the spatial distribution of the KISS galaxies. Many are found to reside in regions of low galaxian density, including several well within the Boötes Void.
