Description :
The data set contains spectra of rotational emission of 12CO, 13CO, C18O (J=1-0), CS (2-1), and N2H+ (J=1-0) for 159 low-mass sources from the dense-core catalogue of the Galactic Cold Cores programme (Montillaud et al. 2015, A&A). The spectra were obtained by pointed observations using the Onsala 20m radiotelescope (Sweden). The observation programme aims at characterising low-mass sources, to investigate their role in the star formation process, particularly for low-mass stars.

Formats : application/fits
Data acquisition methods :
  • Observational data :
    Pointed observations with the OSA (for CO isotopologues and CS) and SPE (for N2H+) instruments on the Onsala 20m telescope. Spectral resolutions are between 5 kHz and 80 kHz and sensitivity of the order of RMS(Ta*) = 50 mK (down to 20 mK at 12 kHz resolution for some N2H+ observations).
