Abstract
We present observations of the region between -45 degrees less than or equal to l less than or equal to -10 degrees and \b\ less than or equ al to 3 degrees in the OH 1612.231 MHz line, taken in 1994 January wit h the Australia Telescope Compact Array (ATCA)(1). These observations are part of a larger survey, covering \I\ less than or equal to 45 deg rees and \b\ less than or equal to 3 degrees, with the ATCA and the Ve ry Large Array. In a previous article we have discussed the observatio nal strategy in detail. In this paper we present only the objects foun d in this part of the survey. The region was systematically searched f or OH-maser emission and was covered completely with 910 pointing cent res 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-pe aked spectral profile, 32 a single-peaked profile and 4 objects have n on-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(2).
