Notes. Observation results of each line in 32 VLA pointings. ◯ means that the flux peak of the emission line is larger than 3σ (detected); × means that the range of the correlator setting not contain this line. For the undetected line, we mark its the upper limit at the 1σ in mJy beam−1. The correlator is configured to cover the frequency range of 18–26.5 GHz, and the spectral resolution is 15.625 kHz (about 0.2km s−1 in this band). The rest frequencies of those lines are (in GHz): NH3(1, 1) in 23.694, NH3(2, 2) in 23.723, NH3(3, 3) in 23.870, NH3(4, 4) in 24.139, NH3(5, 5) in 24.533, NH3 (6, 6) in 25.056, NH3 (7, 7) in 25.715, NH2D (4, 4) in 25.024, NHD2 (6, 7) in 23.023, CCS (21, 12) in 22.344, CCS(56,55) in 24.506, HC9N–1(40, 39) in 23.241, HC9N–2(41, 40) in 23.822, H64α in 24.509, CH3OH(62, 61) in 25.018, H2O(616, 523) in 22.235, NH3–sp(2, 2) in 23.099, CC34S (2, 1) in 25.344, D2O (3, 4) in 20.460, C13CS(2, 1) in 25.783.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
