On-source observing times were between 30 and 375 minutes. The range in observing times is large because data obtained in service mode (most of the sample) were not always completed. As a consequence of this and varying spectral bands and observing conditions, the depth of our observations ranges between rms$=$0.8 and $2 \times 10^{-17}$ erg s$^{-1}$ cm$^{-2}$ Å$^{-1}$ arcsec$^{-2}$, for a circular aperature with 1 diameter and after smoothing spatially by 3$\times$3 pixels, akin to our data cubes prior to analysis. In spite of this, we detected line emission from all galaxies at least in one band, including those with the shortest exposure times. With very short exposures we may however have missed faint, extended line emission in some cases. Observing parameters and exposure times of individual sources are listed in Table \[tab:sample\]. We also point out in our descriptions of individual sources in Appendix \[sec:individualobjects\] which sources might be affected.
