OH/IR stars close to the Galactic Centre. I. Observational data.
Abstract
The results of a search for OH/IR stars close to the Galactic Center using the VLA are presented. Six primary beam fields have been observed with three frequency settings covering +/- 217 km/s. 134 OH sources were identified as OH/IR stars. 16 OH sources were detected having only one line component. This paper discusses the observations and data reduction and presents the spectra of the sources. The distribution of the stars on the sky is clearly elongated with the major axis parallel to the galactic equator. The stars seem to take part in the rotation of the Galaxy but show strong deviations of up to 200 km/s from the mean radial velocity.
