Description:
The results of calibration of the surface brightness, bolometric flux
and effective temperature scales are presented for 537 dwarfs and
giants selected as standards for the Infrared Space Observatory (ISO).
Individual temperatures with small model-dependent corrections are
derived at the target accuracy of 1%. The comparison with
semiempirical values achieved by the Infrared Flux Method (IRFM) shows
consistent results within the 1% level for F, G and K stars, but not
for A-type stars.
