Energy distributions of synthetic spectra for Kurucz model atmospheres are compared with observed energy distributions of metal-deficient stars of the blue horizontal-branch (BHB), F-G-K subdwarf (SD) and G-K giant (MDG) types. The best coincidence of the synthetic and observed energy curves is found for BHB stars. The largest differences are found in the ultraviolet wavelengths for subdwarfs and cool MDGs. The influence of errors of effective temperatures, gravities and metallicities is estimated.
