摘要: A stellar spectral flux library of wide coverage and an example its application are presented. The new consists 131 flux-calibrated spectra, encompassing all normal types luminosity classes at solar abundance, metal-weak metal-rich F-K dwarf G-K giant components. Each spectrum was formed by combining data from several sources overlapping in wavelength coverage. SIMBAD database, measured colors, line strengths were used to check that each input component has closely similar type. complete 1150 10620 Afor components 25000 about half them, mainly later abundance. Missing the infrared currently a smooth energy distribution standard colors for relevant types. is designed permit inclusion additional digital particularly non-solar abundance stars infrared, as they become available. spectra given Fl versus l, Ain steps 5 ˚. program combine ratios appropriate selected isochrone described signature composite population age metallicity illustrated. associated tables available text files remote electronic access.
