Abstract:
This is the second paper in a series studying the star formation
rates, stellar components, metallicities, and star formation histories
and evolution of a sample of blue compact galaxies. We analyzed
spectral properties of 97 blue compact galaxies, obtained with the
Beijing Astronomical Observatory (China) 2.16m telescope, with
spectral range 3580Å-7400Å.
We classify the spectra according to their emission lines: 13 of the
total 97 BCG sample are non-emission line galaxies (non-ELGs); 10 have
AGN-like emission (AGNs), and 74 of them are star-forming galaxies
(SFGs). Emission line fluxes and equivalent widths, continuum fluxes,
the 4000A Balmer break index and equivalent widths of absorption lines
are measured from the spectra.

Note on table1.dat and table2.dat: There are 74 star-forming BCG (SFG)
in our sample, but the spectrum of I Zw207 has not 3600-4100Å,
and the spectrum of IIZw67 has no Hβ emission line.
Note on table3.dat: V II Zw 631 has not Hβ lines, and is not
included in table3.
