All Tables

• Table 1: Field O stars in newly detected clusters. The asterisk indicates that the star is found in a region with star formation signposts (see Sect. 4.3). In Col. 2 we give the visual multiplicity (VM) of the stars, adopted from M98 and G87; VMS = Visual Multiple Star. In Col. 3 we use the following abbreviations for the spectroscopic multiplicity (SM): C = constant radial velocity, SB1 = single-lined spectroscopic binary, SB2 = double-lined spectroscopic binary. Addition of an "O'' and/or "E'' indicates that the orbit is known and/or an eclipsing system. A colon indicates uncertainty.
• Table 2: Runaway O-type candidate stars derived from Hipparcos proper motions and distance from Galactic plane (Z). The abbreviation in Cols. 2 and 3 are the same as in Table 1 and OPT = optical binary, VB = visual binary. The criterion for classification of the listed stars as candidate runaway stars is given in the last column.
• Table 3: Field O stars possibly associated with young clusters. See Tables 1 and 2 for the meaning of the abbreviations used in Cols. 2 and 3. The projected distance is with respect to the distance of the field O star.
• Table 4: The final 11 O-type field stars that could not be associated with clusters. An asterisk indicates if the surrounding field shows signs of star formation as reported in Paper I. The abbreviations are the same as in Tables 1 and 2.
