Towards global-phase-delay VLBI astrometry: observations of QSO 1150+812 and BL 1803+784
M. A. Perez-Torres, J. M. Marcaide, J. C. Guirado +4
On 18 November 1993, we observed the QSO 1150+812 and the BL Lac object 1803+784, nearly 15°apart on the sky, with a VLBI array, simultaneously recording at 8.4 and 2.3 GHz. Using…
