Description:
We present the fourth list with results of the Hamburg/SAO Survey for
Emission-Line Galaxies (HSS hereafter, SAO -- Special Astrophysical
Observatory, Russia). The main goal of the project is the search for
emission-line galaxies (ELG) in order to create a new deep sample of
blue compact/HII galaxies (BCG) in a large sky area. Another important
goal of this work is to search for new extremely low-metallicity
galaxies. The main ELG candidate selection criteria applied are blue
or flat enough continuum (near 4000Å) and the presence of strong or
moderate emission lines close to 5000Å recognized on digitized
prism spectra of galaxies with the survey estimated B-magnitudes in
the range 16-19.5. No other criteria were applied. The list is a
result of the follow-up spectroscopy conducted with the 6m SAO RAS
telescope in 1998, 1999 and 2000. The data of this snap-shot
spectroscopy survey confirmed 127 emission-line objects out of 176
observed candidates and allowed their quantitative spectral
classification. We could classify 76 emission-line objects as BCG/HII
galaxies or probable BCGs, 8 as QSOs, 2 as Seyfert galaxies, 2 as
super-associations in a subluminous spiral and an irregular galaxy,
and 37 as low-excitation objects - either starburst nuclei (SBN), or
dwarf amorphous nuclei starburst galaxies (DANS). We could not
classify 2 ELGs. Furthermore, for 5 galaxies we did not detect any
significant emission lines. For 91 emission-line galaxies, the
redshifts and/or line intensities are determined for the first time.
Of the remaining 28 previously known ELGs we give either improved data
on the line intensities or some independent measurements.
