H2CO and OH line observations of the Chamaeleon I dark cloud.
Abstract
The first extensive radio line mapping of the Chamaeleon I dark cloud is reported. The Parkes 64-m radio telescope was used to map the 6-cm formaldehyde absorption and the 18-cm OH emission, with grid spacings of 6arcmin and 10arcmin, respectively. There are three reflection nebulae associated with the cloud, two of them with B-type illuminating stars. There is no correlation (or anticorrelation) of the H2CO line parameters with these nebulae.
