Caption: Figure 11.

Sky positions of the two SMC carbon-rich PPNe are shown superimposed on an image (4 fdg44 × 6 fdg11) of the SMC in the Spitzer [3.6] filter. The image is oriented so the Magellanic Stream runs off to the left of the image, hence the vertical axis runs from northeast to southwest on the sky (top to bottom). The blue dot shows the position of the 21 μm object J004441. The green square marks the position of the other carbon-rich PPN J010546 which may have a weak 21 μm feature. The image is centered at α = 00 h56 m17 fs155, δ = −72°57′10 farcs23 (J2000) and is rotated −31 fdg6 east of north.
