... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....

Comment on J0627-3529 . We have detected the core of an FR-I object and early-type galaxy (Venturi et al. 1995). The core is 0.54 Jy at 2.3 GHz on the Parkes-Tidbinbilla baseline (Morganti et al. 1997) and 0.6 Jy at 5 GHz (VLA data, Ekers et al. (1989) and Morganti, Killeen & Tadhunter (1993)). The VLBA image at 2.3 GHz with the resolution of 15x9 mas shows a "core-jet" structure, with the core brightness of 494 mJy/beam (Venturi et al. ...

CLEAN Map ps -- is a plot of the naturally weighted CLEAN image. The lowest contour levels (2 steps) on image is plotted at "clev" levels [Jy/beam], the peak brightness -- "max" values [Jy/beam]. The dashed contours indicate negative flux. The beam is shown in the bottom left corner of the images. The plot is in postscript format.
