The J−H, H−Ks color−color diagram of the shell (upper panel) and background objects (lower panel) in F14. Filled circles mark the observed stars and boxes mark the stars behind the globulettes. Asterisks mark stars with only H−Ks colors. The crosses in the bottom righthand corner indicate the maximum (left) and the average error (right). A reddening vector of 3^m is indicated. The names refer to the eastern and western jaw of the Wrench. The numbering starts from the tip of the jaw. The corresponding coordinates are (in J2000.0) (1): 6:31:34.49, 5:07:01.8; (2): 6:31:34.44, 5:07:07.6; (3): 6:31:33.60, 5:07:32.0; (4): 6:31:34.03, 5:07:41.4; (5): 6:31:33.34, 5:07:40.4; (6): 6:31:32.95, 5:07:45.2. East-base refers to the most reddened star in the base of the eastern jaw. Its coordinates are 6:31:38.06, 5:08:06.0 (J2000.0).
