The integrated NH3(1, 1) emission (TMBdv) of the molecular core SS2 (source A) and two serendipitously detected cores (sources B and C). White dots mark measured positions; crosses indicate the location of the IR sources IRAS 18264–0143 and IRAS 18264–0142 (Beichman et al. 1988), and stars determine Class 0 protostars (Maury et al. 2011). The (0, 0) map position is RA = 18:29:05.1, Dec = −01:42:00 (J2000).
