J/A+A/393/115      86GHz SiO maser survey of late-type stars (Messineo+, 2002)

86 GHz SiO maser survey of late-type stars in the Inner Galaxy. I. Observational data Messineo M., Habing H.J., Sjouwerman L.O., Omont A., Menten K.M. <Astron. Astrophys. 393, 115 (2002)> =2002A&A...393..115M

These stars were selected on basis of their infrared magnitudes and colours from the ISOGAL and MSX catalogues. SiO maser emission was detected in 271 sources, and their line-of-sight velocities indicate that the stars are located in the Inner Galaxy. These new detections double the number of line-of-sight velocities available from previous SiO and OH maser observations in the area covered by our survey and are, together with other samples of e.g. OH/IR stars, useful for kinematic studies of the central parts of the Galaxy. Description: The results of the 86GHz SiO maser survey are presented in two tables. The 271 SiO maser detections are listed in table2.dat, while the 173 sources with no SiO maser detected are listed in table3.dat. The entries are arranged according to increasing right ascension. The conversion factor from antenna temperature to flux density is 6.2Jy/K. File Summary:
