Table 3

Line fluxes of isotopologues of H₂O in the observed SPIRE range.

Table 4

Line fluxes of isotopologues of H₂O in the observed PACS range.

Appendix A: Line flux ratios

This section of the appendices shows the line flux ratios of HO/HO. We note that since the HO is not detected, we give lower limits to the line ratios. In the case when both isotopologues are not detected, the ratios are set to 1.0.

Table A.1

Line flux ratios of HO/HO observed by Herschel-HIFI.

Table A.2

Line flux ratios of HO/HO in the observed PACS range.

Table A.3

Ratios of HO/HO line fluxes observed with SPIRE.

Appendix B: Compilation of observed SPIRE line fluxes

We present a table with line fluxes for the SPIRE spectra of extreme OH/IR stars.

Table B.1

Line fluxes of all lines detected in the observed SPIRE range.

Appendix C: Compilation of observed PACS line fluxes

We present tables for the list of lines detected in the PACS spectra for individual objects.

Table C.1

Line fluxes calculated from PACS spectra of AFGL 5379.

Table C.2

Line fluxes calculated from PACS spectra of OH 26.5+0.6.

Table C.3

Line fluxes calculated from PACS spectra of OH 30.1-0.7.

Table C.4

Line fluxes calculated from PACS spectra of OH 32.0-0.5.

Table C.5

Line fluxes calculated from PACS spectra of OH 32.8-0.3.

Table C.6

Line fluxes calculated from PACS spectra of OH 42.3-0.1.

Appendix D: SPIRE spectra

This section shows the continuum subtracted apodized SPIRE spectra (in W m^-2μm^-1) of the stars in our sample (histogram) together with the Gaussian fits for H₂O (red), HO (blue), CO (green) and H₂S (yellow). Other molecules are shown in cyan.

Appendix E: PACS spectra

This section shows the continuum subtracted PACS spectra (in W m^-2μm^-1) of the stars in our sample (histogram) together with the Gaussian fits for H₂O (red), HO (blue), and CO (green). Other molecules are shown in cyan. We note that no circumstellar emission lines are detected in the spectrum of OH 21.5+0.5. The PACS spectrum of OH 127.8+0.0 has already been publish by Lombaert et al. (2013) and is not presented here.
