Abstract:
We present an 86GHz SiO (v=1, J=2->1) maser search towards late-type
stars located within |b|<0.5° and 20°<l<50°. This search
is an extension at longer longitudes of the work by Messineo et al.
(2002, Cat. J/A+A/393/115). We selected 135 stars from the MSX catalog
using color and flux criteria and detected 92 (86 new detections). The
detection rate is 68%, the same as in our previous study. The last few
decades have seen the publication of several catalogues of point
sources detected in infrared surveys (MSX, 2MASS, DENIS, ISOGAL, WISE,
GLIMPSE, AKARI, and MIPSGAL). We searched each catalogue for data on
the 444 targets of our earlier survey and for the 135 in the survey
reported here. We confirm that, as anticipated, most of our targets
have colors typical of oxygen-rich AGB stars. Only one target star may
have left the AGB already. Ten stars have colors typical of
carbon-rich stars, meaning a contamination of our sample with carbon
stars of ≤1.7%.
Description:
The results of the 86GHz SiO maser survey at 20°<l<50° are
presented in two tables.
The 92 sources with detected 86GHz SiO maser emission are listed in
table1.dat, while the 43 sources not detected at 86GHz are listed in
table2.dat. The entries are arranged according to increasing right
ascension. The conversion factor from antenna temperature to flux
density is 6.2Jy/K. Infrared photometry of the targeted stars in
Tables 1 and 2 of this work and in Tables 2 and 3 of (Messineo et al.,
2002, Cat. J/A+A/393/115) are presented in table3.dat. Measurements
are collected from the MSX, 2MASS, DENIS, ISOGAL, WISE, GLIMPSE,
AKARI, and MIPSIGAL.
A list of the brightest targets with the computed luminosities is
provided in tablec1.dat.

Note (1): Identification numbers as from Tables 1 and 2 of this work,
and from Tables 2 and 3 of Messineo et al. (2002, Cat. J/A+A/393/115).
Note (2): Generally 2MASS coordinates are provided (see also Note 5).
Note (3): Nstar is a flag that concatenates the number of MSX point sources
detected within a radius of 14.5" (first digit), the number of WISE point
sources detected within a radius of 10.0" (second digit), and the number of
preselected GLIMPSE point sources within a radius of 10.0" (third digit).
For example, Nstar=111 means that in the searched circle we found
only 1 MSX star, 1 WISE, and 1 bright GLIMPSE.
Exception: when the second digit is 9, it means that no WISE target was found
in the AllWISE Data Release, and the adopted magnitudes come from the
older WISE All-Sky Data Release.
Note (4): * for targets for which multiple WISE sources fall within the beam.
There is a small chance that the selected counterparts are not the actual
masing stars.
Note (5): Note as follows:
ul = 2MASS JHKs magnitudes are missing or blended in 2MASS
uk = UKIDSS coordinates and magnitudes are provided
Note (6): Magic values are set as follow:
99.99 = general indicator of a missing entry
98.98 = upper limits
97.97 = blending ((i) automatically identified by having found multiple WISE
stars or multiple GLIMPSE bright stars at this position;
(ii) datapoints removed after visual image inspection because of
astrometric offsets due to stellar blending or strong nebular
emission
96.96 = area not covered by the survey
95.95 = faint source not detected
94.94 = datapoints removed because very offset from the SED defined by the
other datapoints
93.93 = magnitude above the saturation limit
88.88 = no magnitude was found, but the corresponding image is saturated
(bright target)
Note (7): For star #294, there are additional JHK measurements from
Cabrera et al. (2006A&A...453..371C 2006A&A...453..371C, Cat. II/270) that well agree with the
2MASS (J=11.333, H=7.346, K=5.442mag). This suggests that the DENIS Ks
measurement (7.73mag) could be affected by artefact.
