IVS name - the 8 letters long name of the source adopted by the International VLBI Service for Geodesy and Astrometry. This is either IAU B1950 name of a common name.
J2000 name - a 10 letters long name of the source in notation Jhhmmdddmm where hhmm are hours and minutes in right ascension, dddmm are degrees and minutes in declination at the J2000.0 epoch. No rounding is performed.
J2000.0 кординаты - source coordinates in J2000.0 epoch: right ascension and declination. Currently, the proper motion is assumed to be zero for all sources.
CLEAN карта gif - is a plot of the naturally weighted CLEAN image. The red dashed contours indicate negative flux. The beam is shown in the bottom left corner of the images. The plot is in GIF format.
CLEAN карта 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.
