The integrated intensity (moment 0) maps of all the nonmasing transitions detected in W51-IRS2. Contour levels in red for the integrated flux density of different transitions are 0.05, 0.1, 0.2, 0.4, 0.6, 0.8, 1.0, and 1.2 Jy beam−1 km s−1, while those in blue are 0.2 and 0.5 times the peak of the integrated flux density for each transition.
