VizieR Online Data Catalog: Six LMC star forming region spectra (Tang+, 2017)
Abstract
Our observations were carried out in 2008 and 2014 (summarized in Table 1) with the Atacama Pathfinder EXperiment (APEX) 12m telescope located on Chajnantor (Chile) using the APEX-1 (SHeFI) receiver. The beam size is ~30" (~7pc at 50kpc distance) at 218GHz. The main beam efficiency and the forward efficiency were 0.75 and 0.97, respectively. N113 and N159W were observed in 2008 with an old Fast Fourier Transform Spectrometer (FFTS), which consists of two units with a bandwidth of 1 GHz each and a velocity resolution of 0.1675km/s. The frequency is centered at 218.480GHz. Our data includes all three of the 218GHz para-H2CO lines. 30 Dor, N159E, N159S, and N44BC were observed in 2014. Here we used the new eXtended bandwidth Fast Fourier Transform Spectrometer (XFFTS) backend with two spectral windows of 2.5GHz bandwidth and a velocity resolution of 0.1047km/s. The central frequency is set at 218.550GHz. These data do not only include the three para-H2CO lines but also the 219.560GHz C18O (2-1) transition.
