The studies of various types of galaxies with strong current star formation
(SF) are among the most popular in extragalactic astronomy. For many purposes
in this work it is very important to deal with large enough and well
selected samples of such objects. In particular, the authors are involved in
studies of SF bursts in low-mass galaxies (H II-galaxies, or blue compact
galaxies - BCGs), and thus are interested in dealing with large samples
of BCGs. There are three such large BCG/H II galaxy samples on the northern
sky, each covering about 1000 square degrees. The first one is situated in
the zone of the Second Byurakan Survey (Markarian et al. [1983],
Stepanian [1994])
(

).
It is described partly by Izotov et al. ([1993a], [1993b]),
Thuan et al. ([1994]) and Pustilnik et al. ([1995]).
The second one is under completion (Salzer et al. [1995],
Ugryumov [1997], Ugryumov et al. [1998]) and
is situated in a region, which is a part of the Case objective prism survey
(
,
)
(Pesch et al. [1995]).
The third one, the Heidelberg void survey (Popescu et al. [1996],
[1998]), is located in two separated regions.
The new Hamburg/SAO Survey for Emission-Line Galaxies is intended to cover
the gap between the regions of the SBS and the Case survey and to create a
new BCG/H II galaxy sample in that region. It covers the region between
7h 20m to 17h 40m in right ascension and between
to
in declination.
This is the second article of the series devoted to follow-up spectroscopy
results of preselected ELG Hamburg/SAO candidates.
The basic ideas of the Hamburg/SAO survey and the selection methods of ELG
candidates are described along with the first results of follow-up
spectroscopy in Ugryumov et al. ([1999]) (Paper I).
This article is organized as follows. In section 2 we give the details of
the 6m telescope spectroscopic observations and of the data reduction.
In section 3 the results of the observations are
presented in several tables. Along with general parameters for
emission-line galaxies and several quasars the parameters of the strongest
emission lines are summarized in a separate table. The information on
several non emission-line galaxies is presented as well.
In section 4 we briefly discuss the new data and summarize the current
state of the Hamburg/SAO survey. Throughout this paper a Hubble
constant H0 = 75 kms-1 Mpc-1 is used.
