In-flight calibration of the ROSAT HRI ultraviolet sensitivity.
BARBERA M., MICELA G., COLLURA A., MURRAY S.S.A. and ZOMBECK M.V.
Abstract (from CDS):
Comparing measured and estimated count rates of a few selected sample stars, we confirm the validity and provide the in-flight calibration of the ROSAT HRI UV/visible effective area model in Zombeck et al. The count rate estimates for Betelgeuse derived with this model are in agreement with the measured HRI upper limit. This result is also confirmed in an erratum by Berghöfer et al. aimed at revising their previous calculation, which was overestimated by more than 2 orders of magnitude. Adopting this ROSAT HRI UV/visible effective area model and measured UV/visible spectra of a set of sample stars covering the range of Teff 3000-40,000 K, we have built the calibration curves to estimate UV/visible contamination count rates for any star of known Teff, mv, and NH.
