The soft X-ray properties of AGN from the CJF sample; A correlation analysis between soft X-ray and VLBI properties
S. Britzen, W. Brinkmann, R. M. Campbell +4
Context: We present the soft X-ray properties obtained in the ROSAT All-Sky survey and from pointed PSPC observations for the AGN in the complete flux-density limited Caltech-Jodre…
The Kinematics of S5 1803+784
N. A. Kudryavtseva, S. Britzen, A. Witzel +8
We present the results of a multi-frequency analysis of the structural variability in the parsec-scale jet of the blazar S5 1803+784. More than 90 epochs of observations at 6 frequ…
Ionospheric Corrections via PIM and Real-Time Data
R. M. Campbell
We describe a method for removing ionospheric effects from single-frequency radio data a posteriori. This method is based on a theoretical climatological model developed by the USA…
VLBI Observations of the Gravitational Lens System 0957+561
R. M. Campbell, J. Lehar, B. E. Corey +2
We present hybrid maps of the A and B images of 0957+561 from each of four sessions of 6 cm VLBI observations that span the six-year interval 1987-1993. The inner- and outer-jets a…
