Abstract:
We present observations of the region between -45{deg}<=l<=-10{deg}
and |b|<=3{deg} in the OH 1612.231MHz line, taken in 1994 January with
the Australia Telescope Compact Array (ATCA). These observations are
part of a larger survey, covering |l|<=45{deg} and |b|<=3{deg}, with
the ATCA and the Very Large Array. In a previous article we have
discussed the observational strategy in detail. In this paper we
present only the objects found in this part of the survey. The region
was systematically searched for OH-maser emission and was covered
completely with 910 pointing centres separated by 30'. We found 202
OH-masing objects, 112 of which are new detections. Out of the 202
objects, 166 have a standard double-peaked spectral profile, 32 a
single-peaked profile and 4 objects have non-standard or irregular
profiles. In this article we analyse the data statistically and give
classifications and identifications with known sources where possible.
The astrophysical, kinematical, morphological and dynamical properties
of subsets of the data will be addressed in future articles.
