The ATCA/VLA OH 1612 MHz survey

Abstract

We present observations of the region between and in the OH 1612.231 MHz line, taken in 1994 January with the Australia Telescope Compact Array (ATCA). These observations are part of a larger survey, covering and , 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.
