Abstract:
We present a compilation and study of DENIS, 2MASS, ISOGAL, MSX and
IRAS 1-25 microns photometry for a sample of 441 late-type stars in
the inner Galaxy, which we previously searched for 86GHz SiO maser
emission (Messineo et al., 2002, Cat. J/A+A/393/115). The comparison
of the DENIS and 2MASS J and Ks magnitudes shows that most of the SiO
targets are indeed variable stars. The MSX colours and the IRAS
[12]-[25] colour of our SiO targets are consistent with those of Mira
type stars with dust silicate feature at 9.7 microns feature in
emission, indicating only a moderate mass-loss rate.
Description:
A catalogue of infrared photometry from DENIS (bulge PSC), 2MASS (all
sky data release), ISOGAL (PSC 1.0), MSX (PSC 1.2) and IRAS (PSC 2.0)
is presented for a sample of stars which we previously searched for
SiO maser emission. The identification source numbers (e.g #99) are
taken from Table 2 (86GHz SiO maser detections) and Table 3
(non-detections) in Messineo et al. (2002, Cat. J/A+A/393/115). The
number of targeted positions searched for SiO maser emission in
Messineo et al. (2002, Cat. J/A+A/393/115) is 441. As three
positions showed a double 86GHz SiO maser detection, the line
identification number goes up to 444. For two of these three
positions, we were able to identify two distinct possible infrared
counterparts within the IRAM beam.

Note (1): ID as in Messineo et al. (2002, Cat. J/A+A/393/115).
At three positions we found two SiO maser detections (21-22, 64-65 and
77-78). For only 21-22 and 77-78 we were able to identify two distinct
possible infrared counterparts within the IRAM beam. The targeted star
is brighter at mid-infrared wavelength than the second mid-infrared
star in the beam and is therefore associated with the strongest line.
Note (2): Variability flags :
2: variability is detected in at least one of the datasets,
1: variability is not detected but not all the datasets were available
0: variability is not detected in any of the datasets.
Note (3): A value of 88.88 for a magnitude means that no magnitudes
was found but the corresponding image is saturated at this position,
while a value of 99.99 means that the source was not detected at this
wavelength.
Note (4): A value of 99.9 means that the source was not detected in
the MSX survey.
