Due to a wrong conversion of flux units in the infrared (IR) spectral range, the H2 profiles were erroneously reported with a flux a factor of 10 higher than the correct one.

The values of the H2 peak intensities, fluxes, and luminosities in Tables 3, 4, and A.1 have now been corrected. Here we also publish Figs. 1, 2, 5, 6, 7, and A.1 with the correct flux scale.

Consequently, the second paragraph of Sect. 5.3, should read as follows: “From Fig. 5 we see that about half of the sources where H2 has been detected have a similar H2 and [OI] luminosity, while in the other half of the sample the H2 luminosity is significantly lower than the [OI] luminosity.”

Example of Gaussian decomposition of continuum-subtracted [O I] and H2 line profiles (black lines). The fit to the profile is in red, while single components are shown with blue dashed lines. Flux units are 10−15 erg s−1 cm−2−1. For each panel, the target name and date of observation (MM.DD.YYYY) are indicated. The complete sample is reported in Fig. A.1.
