Description:
Near-infrared imaging observations of IRAS sources with SiO masers
were made with the 2.3-m telescope of the Australian National
University at Siding Spring Observatory, Australia, on 1997 June
18-23, 1998 June 9-12, and 2000 July 16-19, using the infrared array
camera CASPIR. These infrared observations were made in parallel with
long-term (1997-1999) SiO maser surveys at Nobeyama. The near-infrared
observations were made within a year or so of the SiO detections. The
details of the observations, data reduction, and method of
identification were described in Deguchi et al. (1998PASJ...50..597D 1998PASJ...50..597D,
2001, Cat. J/PASJ/53/293), so they are not repeated here.
All of the sources discussed in this paper are IRAS sources with
detected SiO masers in the sky region of -10°<l<15° and
|b|<3° (Deguchi et al., 2000ApJS..130..351D 2000ApJS..130..351D).
