Notes. For each transition: Col. 1: name of the molecule and set of quantum numbers used; Col. 2: specific quantum numbers; Col. 3: rest frequency; Col. 4: upper level energy; Col. 5: Einstein spontaneus emission coefficient; Col. 6: line flux obtained integrating the area below the profile in main-beam temperature scale; Col. 7: line full width at half maximum (FWHM); Col. 8: main-beam peak temperature and rms for a spectral resolution of ~2 MHz (in parentheses). Columns 7 and 8: were obtained by fitting a Gaussian function to the line core profile, masking the wings. The formal errors given (within parentheses) do not include absolute flux calibration and baseline subtraction uncertainties.
Line blend with SO2173,15−172,16; the value of the flux provided here accounts only for the HNCO line flux, which represents a 75% of the total flux of the blend.
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.
