摘要
The KPNO International Spectroscopic Survey (KISS) is an objective-prism survey for extragalactic emissionline objects. It combines many of the features of previous slitless spectroscopic surveys with the advantages of modern CCD detectors and is the first purely digital objective-prism survey for emission-line galaxies. Here we present the second list of emission-line galaxy candidates selected from our red spectral data, which cover the wavelength range 6400 to 7200 Angstrom. In most cases, the detected emission line is Halpha. The current survey list covers a 1.degrees6-wide strip located at delta = 43degrees30' (B1950) and spans the right ascension range 11(h)55(m) to 16(h)15(m). The survey strip runs through the center of the Bootes void and has enough depth to adequately sample the far side of the void. An area of 65.8 deg(2) is covered. A total of 1029 candidate emission-line objects have been selected for inclusion in the survey list (15.6 deg(-2)). We tabulate accurate coordinates and photometry for each source, as well as estimates of the redshift and emission-line flux and equivalent width based on measurements of the digital objective-prism spectra. The properties of the KISS emission-line galaxies are examined using the available observational data. Although the current survey covers only a modest fraction of the total volume of the Bootes void, we catalog at least 12 objects that appear to be located within the void. Only one of these objects has been recognized previously as a void galaxy.
