- Аннотация: Here we present a set of flexible open-source tools for visualization of spectral and imaging data developed for the VOXAstro projects. Using open-source web visualization libraries we developed interactive viewers to display low- and high-resolution spectra of stars and galaxies, allowing one to view spectra having resolution up to R=80000 without putting a significant load on server and client sides, which is achieved by choosing the adaptive spectral binning window and dynamically pre-loading the datasets. We implemented a number of additional features like multiple spectra display, output of header info (e.g., stellar atmospheric parameters or stellar population properties of galaxies), display of emission lines decomposition parameters (fluxes, widths, etc.). The spectral viewers can be easily embedded into any archive or database web-site. We also present a cutout service that extracts data on the fly from the UKIDSS near-infrared imaging survey and generates colour composite RGB stamps, which we use, e.g., in the RCSED web-site as an embedded service. The service uses IVOA SIAP to access images, which it then cuts out on the fly using Astropy functions. In the coming years we plan to expand the capabilities of our spectroscopic and imaging visualization services and use them in future projects within VOXAstro.
