Spectrophotometry of star-forming regions in HII galaxies

We present spectrophotometric observations of 111 H II galaxies selected from various surveys. Apart from the integrated spectra, we present emission-line fluxes and equivalent widths of different star-forming knots for 33 galaxies for which the spatial distribution of physical properties can be assessed. Most of the objects have been observed previously. We reobserved these galaxies with uniform instrumentation, and data reduction was performed with homogeneous methods. Our analysis of the quality of the data indicates that our observations reach good signal-to-noise ratio over the whole spectral range, allowing the measurement of - and the inclusion of additional - low-intensity emission lines.
