Abstract:
We have performed a wide field survey for dust sources at
1.2-millimetres in the rho Ophiuchi molecular cloud, covering more
than 1 square degree in an unbiased fashion. We detect a number of
previously unknown sources, ranging from extended cores over compact,
starless cores to envelopes surrounding young stellar objects of
Class 0, Class I, and Class II type. We analyse the mass distribution,
spatial distribution and the potential equilibrium of the cores.
Description:
The observations were carried out using the SIMBA bolometer array at
the SEST telescope on La Silla/Chile during an observing run lasting
from 2002 July 7 to 12. SIMBA is a 37-channel bolometer array,
operating at 1.2mm, and provides a HPBW of ∼24" (as measured on maps
of Uranus).

Note (1): The sources are listed in the order they were identified by the
wavelet decomposition plus clumpfind technique.
Note (2): A long dash (---) means that the source is outside the respective
survey area, and "n.i.'' labels features which are visible in the
respective survey, but not identified as a separate feature.
Cross-identifications given in parentheses mean that a feature found
here is a part of a feature noted by Motte et al. 1998A&A...336..150M 1998A&A...336..150M
or Johnstone et al., 2000ApJ...545..327J 2000ApJ...545..327J.
Note (3): Apparently starless features are marked as "sl".
