CMDs of the surveyed area around Palomar 14. The right panel shows the CMD of the innermost 2 4, whereas the left panel shows the CMD of stars located at distances r>15′ to the cluster center. Only stars with a sharpness parameter | S| < 0.2 are plotted. In the left panel, the observed overdensity of stars in the outer field is indicated. The dashed lines indicate the limit below which the sharpness criterion does not provide a good star/galaxy discrimination.
