Appendix A: Tables

Table A.1: The other Galactic Bulge PNe observed with Spitzer/IRS (program $\char93$ 3633).

Table A.2: The rest of PNe (non-Galactic Bulge) observed within Spitzer/IRS program $\char93$ 3633.

Figure B.1:

Spitzer/IRS spectra of Galactic Bulge PNe, which show dual-dust chemistry (see Table 1). The spectral type is shown under name of PN. Note the simultaneous detection of PAH emission features in the 6-14 $\mu$ m range (dashed vertical lines at 6.2, ``7.7'', 8.6 and 11.3 $\mu$ m - right panels) together with crystalline silicate features (dashed vertical lines at 23.5, 27.5 and 33.8 $\mu$ m - left panels).

Figure B.2:

Spitzer/IRS spectra of Galactic Bulge PNe, which show dual-dust chemistry cont. (see Table 1). The spectral type is shown under name of PN; none - means neither [WC] nor wels. Note the simultaneous detection of PAH emission features in the 6-14 $\mu$ m range (dashed vertical lines at 6.2, ``7.7'', 8.6 and 11.3 $\mu$ m - right panels) together with crystalline silicate features (dashed vertical lines at 23.5, 27.5 and 33.8 $\mu$ m - left panels).

Figure B.4:

Spitzer/IRS spectra of Galactic Bulge PNe, which do not show dual-dust chemistry (see Table A.1). The spectral type is shown under name of PN; none - means neither [WC] nor wels. Dashed vertical lines at 23.5, 27.5 and 33.8 $\mu$ m on the left panels mark position of crystalline silicate bands, while those at 6.2, ``7.7'', 8.6 and 11.3 $\mu$ m on the right panels show position of PAH features.

The spectral type is shown under name of PN. Dashed vertical lines at 23.5, 27.5 and 33.8 $\mu$ m on the left panels mark position of crystalline silicate bands, while those at 6.2, ``7.7'', 8.6 and 11.3 $\mu$ m on the right panels show position of PAH features.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
