(P.I.: S. C. Madden). The [PACS]{} array is composed of 5x5 spatial pixels each 9.4$^{\prime\prime}$ square, covering a total field-of-view of 47$^{\prime\prime}$. Haro11 was mapped with 2x2 rasters separated by 4.5$^{\prime\prime}$ in the 7 following fine-structure spectral lines: \[C [ii]{}\] 157 $\mu$m, \[O [iii]{}\] 88 $\mu$m, \[O [i]{}\] 145 $\mu$m (OBSID 1342199236), \[O [i]{}\] 63 $\mu$m, \[N [iii]{}\] 57 $\mu$m, \[N [ii]{}\] 122 $\mu$m (OBSID 1342199237), and \[N [ii]{}\] 205 $\mu$m (OBSID 1342199238), for a total of 7.2h. The \[N [ii]{}\] 205 $\mu$m line was also re-observed on OD 942 for 1.6h with a single pointing (OBSID 1342234063). The observations were done in chop-nod mode with a chop throw of 6$^{\prime}$ off the source. The chopped position is free of emission. The beam size is 9.5$^{\prime\prime}$ at 60 $\mu$m, and 11.5$^{\prime\prime}$ at 150 $\mu$m (diffraction limited above $\sim$100 $\mu$m). The spectral resolution is $\sim$ 90 km s$^{-1}$ at 60 $\mu$m, 125 km s$^{-1}$ at 90 $\mu$m, 295 km s$^{-1}$ at 120 $\mu$m, and 250 km s$^{-1}$ at 150 $\mu$m (PACS Observer’s Manual 2011 [^3]).

The data were reduced with the [*Herschel*]{} Interactive Processing Environment (HIPE) v7.0.1935 [@ott-2010]. We used standard scripts of the [PACS]{} spectrometer pipeline. The line fitting and
