  Vega, Sirius, Beta Leo, Alpha Car and Alpha Cen A belong to a sample of
twenty stellar sources used for the calibration of the detectors of the
Short-Wavelength Spectrometer on board the Infrared Space Observatory
(ISO-SWS). While general problems with the calibration and with the theoretical
modelling of these stars are reported in Decin et al. (2002), each of these
stars is discussed individually in this paper. As demonstrated in Decin et al.
(2002), it is not possible to deduce the effective temperature, the gravity and
the chemical composition from the ISO-SWS spectra of these stars. But since
ISO-SWS is absolutely calibrated, the angular diameter of these stellar sources
can be deduced from their ISO-SWS spectra, which consequently yields the
stellar radius (R), the gravity-inferred mass (M) and the luminosity (L) for
these stars. These deduced parameters are confronted with other published
values and the goodness-of-fit between observed ISO-SWS data and the
corresponding synthetic spectrum is discussed.
