Distribution on the sky of objects from our proper motions catalogue (grey dots) and of the 82 kinematic members and candidates of the ρ Ophiuchi cluster (coloured symbols) derived in this work. Red squares designate class I, green circles class II and blue triangles class III. The zones with few grey dots correspond to the most obscure regions. Crosses indicate the approximative centres of the E, F, and B cores; the dotted line indicates the line of clumps and YSOs identified by Motte et al. (1998).
