VizieR Online Data Catalog: Obs. of Gal. interstellar ratio 18O/17O. I
Abstract
Our observations of the C18O and C17O J=2-1 lines w from 2017 January 11 until January 17, using the IRAM 30m at the Pico Veleta Observatory (Granada, Spain). The center frequencies were set at 219.560354 and 224.714187GHz for the C18O and C17O lines, respectively. With the IRAM 30m, we observed 103 sources of our sample. The observational parameters are summarized in Table 1.
Our Submillimeter Telescope (SMT) 10m (on Mount Graham, Arizona, USA) observations of J=2-1 lines were performed remotely in 2016 May and June, 2018 January and November, 2019 December, 2020 June, July, and November, and in 2021 January and February with a beam size of ~29". Table 1 presents the observational parameters of the SMT 10m results for the sample of 380 sources, including the 62 sources that were observed by both the IRAM 30m and the SMT 10m telescopes.
