Description:
We present a photometric catalogue of seven selected fields
towards the Galactic bulge, observed with the IRAC and MIPS imaging
instruments on-board the Spitzer Space Telescope with unprecedented
sensitivity. The locations of the fields are defined in Figure 1 and
Table 1 of the paper. In each of the fields, tens of thousands of
point sources were detected. The catalogue is split up into seven
tables, according to the different fields. Table 5 in the paper gives
ten lines of the band-merged catalogue of the Bulge N1 field as an
example. In the first paper based on this data set, we present the
observations, data reduction, the final catalogue of sources, and a
detailed comparison to previous mid-IR surveys of the Galactic bulge,
as well as to theoretical isochrones. We find in general good
agreement with other surveys and the isochrones, supporting the high
quality of our catalogue. Besides a catalogue for each field, fits
files of the IRAC and MIPS mosaics are presented, too. As a cautionary
note for the users, we would like to add that the least reliable
sources in our catalogue are those with detection in only one IRAC
band and no MIPS detection, and with (i) either no 2MASS and DENIS
counterpart (depending on the field, between 3.1% and 6.7% of the
sources), or (ii) a DENIS and 2MASS counterpart at a distance between
1.6 and 3 arcseconds (depending on the field, between 0.4% and 1.0% of
the sources).
