The distribution of Markarian galaxies in annular zones at different angular distances θ (degrees) from the centre of the Coma cluster is shown in the Table. the coordinates of the centre for the equinox 1950 are assumed to be α = 12h57m.5, δ = 28°15′. the third, fourth and fifth columns of the Table contain the number of Markarian galaxies in each zone, the solid angle in square degrees and their mean surface densities respectively. It can be seen that an excess surface density of Markarian galaxies exists not only in the very central zone I but in the annular zone II as well. Indeed, the ratio n/ω in zone II is more than twice the value corresponding to the whole area surveyed (and to zones III and IV).
