Soft X-ray standards
Listed in IVOA Registry (Virtual Observatory)
We analyze the Chandra LETG+HRC observations of the white dwarfs HZ43A and Sirius B and of the neutron star RX J185635-3754 with the aim of resolving current uncertainties in the soft X-ray spectral fluxes and photospheric parameters of the three stars.
Description
We apply the derived photon spectra to a cross-calibration of the LETG+HRC-S with the short-wavelength EUVE spectrometer and the ROSAT PSPC.
