Appendix A

H2 column density maps of Lupus I, III, and IV in units of 1020   cm-2 with AV contours overplotted. For Lupus III and IV the contours are AV =  2, 3, 6, and 9 mag, while for Lupus I the contours are 4, 6, and 9 mag (to avoid the stray Moonlight). The different classes of objects, from the Herschel data and from the M08 catalog, are indicated. The off-cloud candidate Class I sources, marked by an asterisk, are those we considered as possible galaxy contaminations (shown by a dashed line in Fig. 3). The one off-cloud Class I in Lupus I without an asterisk has strong 24 μm emission, so is less likely to be a galaxy. Dashed contours mark the Spitzer MIPS coverage.

Visual catalog of the prestellar cores (contour levels are peakflux ∗ 0.99, 0.95, 0.90, 0.80, 0.70, 0.60, and 0.50) and Class 0 objects in the three Lupus clouds (I, III, IV), continued from Fig. 2. The maps are centered on the prestellar core/Class 0 object and are ordered per cloud by right ascension.
