2M++ data and its selection properties. Top left panel: sky completeness at K_2M + + ≤ 11.5, derived as the number of observed redshifts versus the number of targets in the 2MASS photometric sample. Top right panel: same quantity is shown but for apparent magnitudes 11.5 <  K_2M + + ≤ 12.5. Bottom left panel: number count of galaxies in thin radial shells for the two different magnitude cuts shown in the top row. We see that the catalogue covers a volume up to a redshift z ∼ 0.06 − 0.08. Bottom right panel: sky projection of the positions of the galaxies of the 2M++ catalogue. The local large-scale structures are clearly visible.
