Abstract:
We present 86GHz (v=1, J=2-1) SiO maser line observations with the
IRAM 30-m telescope of a sample of 444 late-type stars in the Inner
Galaxy (-4°<l<+30°). 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.
