(1997) have compiled a sample of all quasars with measured radio emission from the Veron-Cetty - Veron catalog (1993, VERON93, CDS/ADC Cat. VII/166) detected by ROSAT (i) in the ALL-SKY SURVEY (RASS, Voges 1992, in Proc. of the ISY Conference `Space Science', ESA ISY-3, ESA Publications, p.9, ADC/<a href="https://cdsarc.cds.unistra.fr/ftp/cats/IX/10">CDS Cat. IX/10</a>), (ii) as targets of pointed observations, or (iii) as serendipitous sources from pointed observations, as publicly available from the ROSAT point source catalog (ROSAT-SRC, Voges et al. 1995, ADC/<a href="https://cdsarc.cds.unistra.fr/ftp/cats/IX/11">CDS Cat. IX/11</a>). The total number of ROSAT detected radio quasars from the above three sources is 654 objects. 69 of the objects are classified as radio-quiet using the defining line at a radio-loudness of 1.0, and 10 objects have no classification. The 5GHz data are from the 87GB radio survey, the NED database, or from the Veron-Cetty - Veron catalog. The power law indices and their errors are estimated from the two hardness ratios given by the SASS assuming Galactic absorption. The X-ray flux densities in the ROSAT band (0.1-2.4keV) are calculated from the count rates using the energy to counts conversion factor for power law spectra and Galactic absorption. For the photon index, the authors used the value obtained for a individual source if the estimated 1 sigma error was smaller than 0.5, otherwise they used the mean value of 2.14. This database was created by the HEASARC in January 1999, based on CDS/ADC Catalog J/A+A/319/413.
