Abstract:
We present a list of 218 additional candidate emission-line objects
discovered with the northern and southern HK interference-filter/
objective-prism survey of Beers and collaborators. The objects have
apparent magnitudes in the range 10<=B<=16, several magnitudes
fainter than obtained with previous prism surveys of similar
resolution. Of the new candidates, 73 have been previously identified.
The total list of HK-survey emission-line candidates now numbers 376
objects, 104 of which were noted by previous surveys.

Note on Comment:
Description of the nature of the detected emission are in three
broad groups: weak (wk), moderate (mod), and strong (str),
corresponding to the strength of the emission feature relative to the
surrounding continuum. Spectra with emission apparent in the cores
of the Ca II H and K absorption features are noted as "core"
emission objects. Spectra with variable emission lines, which means
the strength of the emission appeared to vary across the 90-minute
exposure, are noted as "var". Balmer emission refers to emission
lines detected at the location of the H-8 Balmer line, which is just
visible at the blue edge of the spectra, and occasionally, for
exceptionally strong emission, even in the Halpha line, which is
redward of the nominal filter cutoff. Objects with emission which
did not appear to fall at the location of the Ca II HK features, or
Balmer features are noted as "others."
