Abstract:
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 it 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 4800-5500Å. In most cases, the detected emission
line is [O III] λ5007. The current survey list covers a
1°-wide strip located at δ=29°30' (B1950.0) and spanning
the right ascension range 8h30min to 17h0min. An area of
116.6d°2 is covered. A total of 223 candidate emission-line
objects have been selected for inclusion in the survey list
(1.91°-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.

Note (1): Necessary for locating the KISS ELGs within the survey database tables
Note (2): The formal uncertainties in the coordinates are
0.25" in right ascension and 0.20" in declination.
Note (3): For brighter objects the magnitude estimates have uncertainties
of typically 0.05 magnitude, increasing to ∼0.10 magnitude at B=20.
Note (4): Estimate assumes that the emission line seen in the
objective-prism spectrum is [O III]. Follow-up spectra for 123 ELG
candidates from the current list show that this assumption is correct
in the vast majority of cases. The formal uncertainty in these
redshift estimates is σz=0.0049 (see Section 4.1.3). There are
three objects in the table with negative redshifts listed. In all
three cases the measured value is just slightly negative (i.e., within
the error quoted above), and two of the three have redshifts measured
from follow-up spectra that are both small but positive.
Note (5): Assigned during the line measurement step of the data processing,
is given the value of 1 for high quality sources, 2 for lower quality
but still reliable objects, and 3 for somewhat less reliable sources.
