IRAS point sources with estimated flux densities larger than 1.5 Jy at 7.75 $\mu$m (LW6 filter \[7-8.5 $\mu$m\]) or larger than 0.7 Jy at 6.75 $\mu$m (LW2 filter \[5-8.5 $\mu$m\]) had to be shifted away from the sources and/or the integration time had to be shortened in order to avoid saturating the ISOCAM detectors (see 2.2 below). The selected regions span a wide range of properties (e.g. morphologies, environments), but are all located in nearby molecular cloud complexes (distance $\leq$ 500 pc) either actively forming stars or supposed to be future hosts of star-formation activity.
