Abstrakt: This paper presents a catalog of the energy distribution in the spectra of 263 stars in the wavelength range from 0.4 to 100 m, which are at late stages of evolution and have been observed by the ISO space observatory. For each object in the catalog, estimates of the observed bolometric fluxes were derived from smoothed energy distribution curves. The catalog is available at https://infra.sai.msu.ru/sai%5flss%5fsed both as a table and in machine-readable format. It is shown that for the specified sample of objects, their ISO SWS spectra in the range 2.4–45 m correspond to the general shape of the continuum in only 60 of cases, and can be used without recalibration. A selection of carbon stars, accessible for the infrared observations from the MSU observatories has been made. For some of them the first brightness estimates in the , and bands were obtained with the new IR camera of the 2.5-m telescope of CMO. [ABSTRACT FROM AUTHOR]
