Fig. 3

Spitzer GLIMPSE composite pictures of the IRAS post-AGB star and PN candidates with no near-IR counterparts in the 2MASS PSC (Paper I). The blue, green, and red colors in the composite pictures correspond to the 3.6 μm, 4.5 μm, and 8.0 μm bands, respectively, but for IRAS 17009−4154, IRAS 17443−2949, IRAS 18135−1456, and IRAS 18529 + 0210, for which their saturated 8 μm images were replaced in the red channel by the 5.8 μm images, and for IRAS 17067−3759, for which blue and green correspond to 4.5 μm. The locations of the sources are overlaid on the pictures. North is up, east to the left.
