Abstract (from CDS):

A survey has been made in the SiO J=1-0, v=1 and 2 transitions (∼43 GHz) for the color-selected IRAS sources in the Galactic disk area of 15°<l<25° and |b|<3° with the Nobeyama 45 m telescope. We have detected 67 out of 119 observed sources in SiO masers. Distances to the sources are deduced by the IRAS 12 and 25 µm flux densities and range approximately from 2 to 12 kpc. The lines of sight of this region cross the location of the near end of the bar in the Galaxy. Radial velocities of the detected sources spread between -100 and 200 km.s–1. This range slightly exceeds the possible limits expected from Galactic rotation. A comparison of the SiO with the CO and H I velocity-longitude (v-l) diagrams reveals that the overall distribution of the SiO maser sources on the v-l diagram resembles the molecular ring feature. Observational data are compared with the theoretical results of the bar models.
