VizieR Online Data Catalog: Sgr B2 los molecular absorption line spectra (Corby+, 2018)

Spectra covering transitions of c-C₃H₂, c-H^{1 SO, CCS, H₂CS, HCS+, OH, SiO, 29SiO, H₂CO, H₂(13C)O, l-C₃H, and l-C₃H+ with line-of-sight absorption observed in the 1-50 GHz data from the PRebiotic Interstellar MOlecular Survey (PRIMOS) taken with the Robert C. Byrd Green Bank Telescope (GBT). Data were observed between 2001 and 2014, with the majority of the data obtained in 2007 in GBT Key Science project ID GBT07A-051. Spectra have been baseline-subtracted using best fit polynomials as described in the paper, and normalized by the continuum, so that the y-axis represents (T/T_C-1). Data are provided in the FITS format; each FITS file contains all lines of a single molecule that are observed to have foreground absorption. Please refer to Table 1 of the paper to obtain molecular transition rest frequencies, energies, GBT beam sizes, and transition quantum numbers.}
