Top: projection, on the Galactic plane, of T2Cs within 14 kpc. The Sun is at the vertex of the plot. Black circles with error bars represent the means and standard deviations of the distances projected onto the Galactic plane, in 2° wide angular areas (4° wide for the most peripheral one at positive l). Thirty-four T2Cs were not plotted because they are more distant than 14 kpc. Bottom: same as the top panel, but projected in latitude. The angular areas are 2° wide, except the central one, which is 3° wide.
