“…Several sets of observations were devoted to X-ray sources in Hercules, Leo, Orion, and Taurus. A more detailed description of the mission can be found in Boyarchuk et al (2014), while digitization of Astron data is described in Kilpio et al (2016).…”

Abstract. The purpose of this review is to analyze main directions of creation and functioning of major data sources developed by Russian astronomers or with their participation and to compare them with the worldwide trends in these fields. We discuss astronomical space missions of the past, present, and future (Astron, INTEGRAL, WSO-UV, Spectrum Roentgen Gamma, Lyra-B), high-quality photometric atlases and catalogues, and spectroscopic data sources, primarily VALD and the global VAMDC framework for the maintenance and distribution of atomic and molecular data. We describe collection, analysis, and dissemination of astronomical data on minor bodies of the Solar System and on variable stars. Also described is the project joining data for all observational types of binary and multiple stars, Binary star DataBase (BDB).

“…Some data are absolute, others are relative; data can be given per unit wavelength interval or per unit frequency interval; some authors give intensities while others give magnitudes, etc. Second, all empirical atlases are burdened with systematic errors, leading to large differences in the Balmer jump height and SED's slope, especially in the UV region (see Kilpio et al 2012 for details). To identify these systematic differences, it is advisable to use synthetic photometry, combining SEDs with response curves of different photometric systems, and to compare synthetic magnitudes and color indices to the observed ones.…”

Abstract. Modern spectrophotometric atlases are burdened with significant systematic errors. In particular, the problems of spectrum calibration in the ultraviolet region are not solved; different parts of the spectrum are not thoroughly fit to each other; spectra of (even bright) stars, obtained by different authors, display large discrepancies. Here we discuss a possibility to construct a new atlas of spectral energy distributions (SEDs) for a large set of stars by comparison of empirical stellar spectra in dozens of modern spectrophotometric atlases, as well as the comparison of synthetic and observed color indices in different multicolor photometric systems. In this way we suppose to exclude most of systematic errors and construct a new three-dimensional (spectral class, luminosity class, metallicity) atlas of empirical stellar spectra for several thousand stars. After exclusion of interstellar reddenings, a semi-empirical atlas of average SEDs can be constructed for about 150-200 spectral subtypes. This would allow us to make calibrations of spectrophotometric and photometric parameters in terms of spectral types and physical parameters (T eff , log g, [m/H]) and to verify the accuracy of model stellar atmospheres.
