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 n_BPS:
Asterisk, "*", if present indicates a previous identification is
available. More information about previous identifications can
be found in Table 2 of the printed paper (not included here)
Note on BrCode: The birghtness codes are as follows:
vb = very bright
b = bright
mb = medium bright
m = medium
mf = medium faint
f = faint
vf = very faint
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 CaII 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."
