VizieR Online Data Catalog: Herschel cold clumps CO survey (Feher+, 2017)
Abstract
We present 12CO(1-0) and 13CO(1-0) spectra of 35 co on the infrared mapping of Herschel. The observations were performed with the Onsala 20m telescope. The clumps are located between -30 and 10 degree Galactic latitudes, no closer than ~2 degrees to the Galactic plane and show AV>1.4. The data were taken with the Fast Fourier Transform spectrometer of the telescope with a bandwidth of 100MHz and spectral resolution of 12.2kHz, in frequency throwing mode. The pointing accuracy was around 3 arcseconds. The antenna temperature rms noise is lower than 0.3K in the 12CO spectra and lower than 0.3K in the 13CO spectra. 35 clumps have 13CO data towards the Herschel-derived column density peak and from the 35 clumps, 28 have 12CO data in a five-point cross (with a step size of 33") towards and around the peak. Each 12CO file contains the spectra of the 5-point cross in the next order: 1 = east of the peak, 2 = south of the peak, 3 = peak position, 4 = north of the peak, 5 = west of the peak.
