We present the sixth list with results of the
Hamburg/SAO Survey for Emission-Line Galaxies.
The final list resulted from follow-up spectroscopy conducted
with the 4.5 m MMT telescope in 1996, and with 2.2 m CAHA and 6 m SAO
telescopes in 2000 to 2003.
The data of this snap-shot spectroscopy survey confirmed
134 emission-line objects out of 182
observed candidates and allowed their
quantitative spectral classification and redshift determination.
We classify 73 emission-line objects as definite or probable blue
compact or Hii galaxies (BCG), 8 as QSOs, 4 as Seyfert 1
and 2 galaxies. 30 low-excitation objects were classified as definite
or probable starburst nuclei (SBN), 3 as dwarf amorphous nuclei
starburst galaxies (DANS) and 2 as LINERs.
Due to the low signal-to-noise ratio we could not classify 14 ELGs (NON).
For another 9 galaxies we did not detect any significant
emission lines. For 98 emission-line galaxies, the redshifts and/or
line intensities are determined for the first time.
For the remaining 28 previously-known ELGs we give either improved data
the line intensities or some independent measurements.
The detection rate of ELGs is ~70%.
This paper completes the classification of strong-lined ELGs
found in the zone of the Hamburg/SAO survey. Together with previously known
BCG/ galaxies in this zone, this sample of ~500 objects is the largest to date in a well bound region.
