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. File Summary:

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.
