Fig. C.3
Normalized spectra of OH doublets for all our sources at central position. Doublets at 71 and 98 μm are excluded because of poor calibration of those spectral regions observed with PACS. OH doublet at 84.4 μm is a blend with the CO 31–30 line, whereas OH at 65.13 μm can be affected by H2O 625–514 at 65.17 μm.
