Kernel density estimation plot of the distribution of the complete catalogue (dwarfs + bright galaxies) in the right ascension versus declination plane: four probability density bins are indicated in colour, showing higher probability density in the centre in red and lower density in the outskirts in pale yellow. Dots are overplotted on this distribution to indicate the positions of Type II galaxies in green and Type III galaxies in magenta. The black cross indicates the centre of NGC 1275.
