A large-scale OH sky survey at 1612 MHz. Part I. The observations.
Abstract
Results are presented for a large-scale 1612 MRz OR sky survey. A large range in galactic longitude ( = 12 to 234"), galactic latitude (b = - 2".5 to 2.5), and velocity (VLsR = -200 km s ' to 200 km s-') has been observed. A substantial portion of sky at higher latitudes has also been observed. Approximately 40 previously unknown sources have been discovered and the majority of these have OR characteristics similar to those for OR/IR stars, but few of the sources have known infrared or optical counterparts. Positions and profiles of the new sources are presented in this paper and a discussion of their galactic distribution is given elsewhere. Key words: OR/IR stars - Mira variables - M supergiants - galactic structure
