3.3 GHz ground-state transitions of CH towards southern HII regions. I - an atlas of CH profiles
Abstract
The Parkes 64-m radio telescope equipped with a 3 GHz maser on loan from the Onsala Space Observatory has been used to observe the three ground-state transitions of CH (at 3264, 3335 and 3349 MHz) towards a total of 74 H II regions, mostly at southern declinations. In this paper the regions and related characteristics are listed, and the CH spectra displayed.
