Comparison of VLBI radio-core and X-ray flux densities of extragalactic radio sourcesThe relation between compact radio core and X-ray emission in extragalactic radio sources, suggested by Worral et al. (1987) and Kembhavi et al. (1986), is investigated by comparing the X-ray flux densities observed in 56 extragalactic radio sources with the Einstein Observatory with the compact radio-core flux densities derived from published VLBI maps for these radio sources. It was found that the radio to X-ray spectral index distribution had a small dispersion, whereas the log-log plot of the flux densities showed no correlation. This implies that the basic level of X-ray emission is determined by the radio-core emission, but that the exact value depends on other parameters.
