Abstract

Basic capabilities of the electronic solar spectrum atlas, together with the examples of its usage in observations or during the preparing to them, are presented. The program has been created at the Institute of Solar-Terrestrial Physics based on Liege Solar Spectrum Atlas and Kitt Peak Atlas and covers the spectral range from 3291 to 12000 A. The convenient interface allows us to easily move to the required spectral range in order to obtain information about a spectral line of interest by a single click as well as to search line parameters in the database and to make changes in it. The additional functional abilities have made the atlas useful when calibrating magnetographs and estimating instrumental polarization degree.
