VERY HIGH ANGULAR RESOLUTION IMAGING
Abstract:
We show preliminary results of three of the four radiosource pairs with angular separations ranging from 0.01 degrees to 6 degrees where we have determined such a separation with a typical fractional precision of 10(-8) using phase delays corrected for structural and ionospheric contributions. In the radiosource 4C39.25 we measure a motion with respect to an external radiosource which is compatible with previously reported internal superluminal motion.
