Fig. 7
Two-dimensional number density and histogram projection distributions of the IKN field stars. The histograms have a bin width of 0.345 kpc and are fitted with a Gaussian function shown with solid lines. The outer countour line in the 2D plot indicates a stellar number density of 17.5 ⋆/arcsec2 (16 ⋆/pc2). The white star indicates our best fit position of the IKN centre with an uncertainty of ±150 pc.
