Fig. 2


Model of the phase calibrator used in the final calibration. For better illustration the CLEAN components used (marked by the crosses, the size of each cross indicates the relative associated flux density) were convolved with a circular beam of 2.6 mas FWHM (maximal resolution in right ascension). Contours are (10, 50, 150, 300, 900, 1800) times the rms of 0.46 mJy. Note the slightly extended structure in NE-SW direction.
