Notes. The central position is (l, b) = (28.59°, 3.55°). Offsets are given in Galactic coordinates. The errors shown in parentheses are fitting uncertainties. In cases where no excitation temperature is given, the NH3 (1,1) line is optically thin and does not allow for a determination of this parameter.
