Notes. Therms noise level, σrms, is calculated for channels of 0.8 km s−1 except for the case of H41α for which the channel width is 3.0 km s−1. Rest frequencies are from NIST recommended rest frequencies (Lovas 2004) and the Cologne Database for Molecular Spectroscopy (CDMS, Müller et al. 2001), while Eup and Aij are taken from CDMS. The conversion factor from Jy beam−1 to K in the Rayleigh-Jeans limit is ~23.75 for a frequency of 89.189 GHz.
