VizieR Online Data Catalog: Bok globule BHR 160 radio lines spectra (Haikala+, 2017)
Abstract
Radio spectral lines in maps covering approximately 2' by 2' with 20" spacing and a tilt of 60 degrees of the Bok globule BHR160 are presented. The spectra were obtained at Swedish ESO Submillimetre Telescope (SEST) in 1999. The observed molecular lines were 12CO(1-0), 12CO(2-1), 13CO(1-0), 13CO (2-1), C18O(1-0), C18O(2-1), CS(2-1) and CS(3-2). The SEST 2 and 3mm SESIS and 1 and 3mm IRAM dual SIS SSB receivers and the high resolution 2000 channel AOS spectrometer (channel spacing 41.711kHz) were used. The spectrometer was split into two to observe both channels simultaneously. The observations were made in the frequency switch mode. The switch was 5MHz (the 3mm channels) and 15MHz (the 1 and 2mm channels). The calibration was obtained using the chopper wheel method. The temperature scale of the spectra is in Ta* units, i.e. corrected to outside of the atmosphere but not for beam coupling. The 12CO spectra have been processed to correct for the artefact produced by the frequency switching method by the atmospheric CO and the -5km/s component (12CO (1-0)) and the -5km/s velocity component (12CO(2-1). The spectra are presented in 9 binary table FITS files.
