The KPNO International Spectroscopic Survey ( KISS ) is an objective-prism survey designed to detect 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 ( ELGs ) .
Here we present the third list of ELG candidates selected from our red spectral data , which cover the wavelength range 6400 to 7200 Å .
In most cases , the detected emission line is H \alpha .
The current survey list covers the region of the NOAO Deep Wide-Field Survey ( NDWFS ) .
This survey covers two fields ; the first is 3 \times 3 degrees square and located at RA = 14 ^ { h } 30 ^ { m } , \delta = 34 \arcdeg 30 \arcmin ( B1950 ) , the second is 2.3 \times 4.0 degrees and centered at RA = 2 ^ { h } 7.5 ^ { m } , \delta = -4 \arcdeg 44 \arcmin .
A total area of 19.65 deg ^ { 2 } is covered by the KISS data .
A total of 261 candidate emission-line objects have been selected for inclusion in the survey list ( 13.3 per deg ^ { 2 } ) .
We tabulate accurate coordinates and photometry for each source , as well as estimates of the redshift , emission-line flux and line equivalent width based on measurements of the digital objective-prism spectra .
The properties of the KISS ELGs are examined using the available observational data .
When combined with the wealth of multi-wavelength data already available for the NDWFS fields , the current list of KISS ELGs should provide a valuable tool for studying star-formation and nuclear activity in galaxies in the local universe .
