Abstract:
The nearby Chamaeleon molecular cloud complex is a good laboratory for
studying the process of low-mass star formation because it consists of
three clouds with very different properties. Chamaeleon III does not
show any sign of star formation, while star formation has been very
active in Chamaeleon I and may already be finishing.
Our goal is to determine whether star formation can proceed in Cha III
by searching for prestellar cores, and to compare the results to our
recent survey of Cha I.
Description:
The 870 micron dust continuum emission map of the Chamaeleon III
molecular cloud displayed in Fig. 2 is available at CDS in FITS
format. The data were obtained with the bolometer camera LABOCA at the
APEX telescope. They were calibrated, reduced, co-added, gridded,
smoothed to an effective angular resolution of 21.2" (FWHM), and
written in FITS format with the BoA software. The flux density unit is
Jy/21.2"-beam. The coordinates are equatorial (J2000) and the offsets
are in RADIO projection.
