Same as Fig. A.1, but for the L673 region. The NH₃ lowest contour level is 0.45 K and the increment is 0.3 K. The NH₃ map obtained in previous observations is also included. The IRAS sources associated with the ammonia structure are (from north to south) IRAS 19180+1116(=RNO 109), IRAS 19180+1114 and IRAS 19184+1118. The map of the CO molecular outflow is from Armstrong & Winnewisser (1989).
