Spectral fits to the OH 119 μm absorption lines in the galaxies Zw 049.057, IRAS 20414–1651, and NGC 7469. The solid black histograms represent the data, the solid magenta lines indicate the best multicomponent fits to the data, and the dashed blue lines represent the individual components. The velocity scale is set relative to the frequency of the blue component of the doublet. Dashed vertical lines indicate the expected positions of the two absorption components given the adopted redshifts.
