Abstract:
We present emission-line strengths for 394 galaxies from the
field-galaxy redshift surveys of Kirshner, Oemler, and Schechter
(1978, Cat. J/AJ/83/1549, KOS) and Kirshner et al. (1983,
Cat. J/AJ/88/1285, KOSS) as part of a study of the nature of field and
void galaxies. These data are 95% complete in their coverage of the
[O III]λλ5007,4959 emission lines. We find that
8.8%±1.5% of a J magnitude-limited data set have [O III]λ5007
emission equivalent widths greater than 10A. There is no evidence
that the spatial distribution of emission-line galaxies in each field
differs from that of galaxies without emission. However, there is a
significant increase in the fraction of galaxies with strong [O III]
emission in the southern fields of the Kirshner, Oemler, and Schechter
(1978, Cat. J/J/83/1549) survey as compared with the other survey
fields. Our results are consistent with the conclusion that the
fraction of galaxies with emission is larger in the Bootes void than
in the general field, but tighter constraints on the void normal
galaxy population are needed to improve the statistics.

Note (1): a: Emission contaminated by cosmic ray
b: Emission from a southern HII region on photographic plate was not
found by follow-up reticon scan.
Note (2): A blank indicates that the coverage did not include that line
Hα is often Hα, [N II] blend
Note (3): N: the line was not detected at the noise level of the spectrum
