“…In the current stage detailed investigation of separate objects of the basic sample is being carried out, the basis of which are the results of the panoramic spectroscopy with the coverage of spectral range, which includes the recombination Hα line of hydrogen and at least its nearest forbidden doublets of the nitrogen [NII]λλ6548,6583 and sulfur [SII]λλ6717,6731 lines. The observations were started from the most interesting by morphology galaxies with the usage of multipupil spectrographs MPFS and VAGR, with the 6-m telescope of SAO and the 2.6m telescope of BAO, respectively (e.g., Hakopian et al 2006, Hakopian et al 2012. The development of more detailed scheme of classification of starforming galaxies is within the goals connected to further explorations of our basic sample.…”

The main criterium for the selection of active objects in the First Byurakan Survey was the presence of uv-excess on low-dispersion spectra registered on photographic plates obtained with the 1m Shmidt type Byurakan telescope. Using the presence of emission lines as the second criterium became possible during the Second Byurakan Survey due to its improved technique. Through this criterium a majority of objects, extended by morphology, were selected into the separate "sample of galaxies". Certainly, there were cases of untrue selection, particularly, on faint magnitudes, when absorption lines were taken for emission ones and so on. Study of SBS galaxies, including evaluation of an effectivity of selection criteria, was undertaken by means of complex investigation of their very representative part, pooled in our basic sample. The completion of the follow-up slit spectroscopy of these about 500 objects formed the main stage of implementation of this program. Also, the scheme was developed to provide homogeneous classification, directed, in particular, to separate galaxies of AGN activity, of known types, and starforming, SfG, activity. For starforming galaxies, which constitute more than 80% of the basic sample, we provided two classes, SfGcontinual and SfGnebular. Averaged statistics of our SfG galaxies show, that every fifth of them is in more active, nebular phase of starforming activity, most of which are known as blue compact galaxies. However, it must be noted, that, by the analysis, namely for the latter objects, the effectiveness of the survey is the highest, so that BCGs represent the best product of SBS among extended objects. Aimed on further specifications in classification of SfG galaxies, other generalizations and statistics in frames of ongoing investigation, detailed studies of individual galaxies are currently beeing held, based on data of panoramic spectroscopy.Comment: 5 pages, 2 figures, 2 tables (extended version), prepared for the Conference Proceedings of IAU Symposium 304 "Multi-wavelength AGN Surveys and Studies" (Yeravan, Armenia, October 1-6, 2013

The methods of panoramic (3D) spectroscopy are used by us in a detailed study of galaxies with ongoing star formation chosen from among objects in seven selected fields of the Second Byurakan Survey (SBS). This article deals with the irregular galaxy SBS 1202+583, which our classification scheme identifies as being in a continuous phase of star formation. Observations were made with the panoramic spectrographs MPFS at the 6-m telescope of the Special Astrophysical Observatory (SAO) of the Russian Academy of Sciences and VAGR at the 2.6-m telescope of the Byurakan Astrophysical Observatory (BAO) in Armenia.The data are used to construct maps of the radiative fluxes in the continuum and various emission lines. Special attention is devoted to analyzing the emission in the Hα
