The KPNO International Spectroscopic Survey ( KISS ) is an objective-prism survey for extragalactic emission-line 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 first list of emission-line galaxy candidates selected from our blue spectral data , which cover the wavelength range 4800 – 5500 Å .
In most cases , the detected emission line is [ O iii ] \lambda 5007 .
The current survey list covers a one-degree-wide strip located at \delta = 29 \arcdeg 30 \arcmin ( B1950.0 ) and spanning the right ascension range 8 ^ { h } 30 ^ { m } to 17 ^ { h } 0 ^ { m } .
An area of 116.6 deg ^ { 2 } is covered .
A total of 223 candidate emission-line objects have been selected for inclusion in the survey list ( 1.91 deg ^ { -2 } ) .
We tabulate accurate coordinates and photometry for each source , as well as estimates of the redshift , emission-line flux , and equivalent width based on measurements of the digital objective-prism spectra .
The median apparent magnitude of the sample is B = 18.2 , and galaxies with redshifts approaching z = 0.1 are detected .
The properties of the KISS emission-line galaxies are examined using the available observational data , and compared to previous surveys carried out with photographic plates as well as with the H \alpha -selected portion of KISS .
