a) Distribution of integrated NH3(1, 1) emission (white contours) towards LDN 1569 (Effelsberg data) superposed on the integrated 13CO(1–0) emission (colour plot; black contours) observed with the SEST. The NH3 contour levels are 0.05 (0.05) 0.20 K km s-1 (dv) and the 13CO contour levels 0.45 (0.45) 1.8 K km s-1. Black dots indicate positions observed in 13CO and white circles those observed in NH3.
