Table 7:
Membership and photometry of Per OB2. We first list the 29
objects observed by us (cf. Table 1). Below the horizontal
line, we added two classical members from B52 that were not observed
(Sect. 5.2.1) and three members from Z99 for which
literature radial velocities exist
(Sect. 5.2.3). Columns:
(1) HD number;
(2) spectral type;
(3) classical membership assignment (B52; C: certain member; P:
possible member; N: non-member);
(4) Hipparcos membership (Z99);
(5) membership based on radial velocity (mostly this work);
(6) final membership, based on Cols. 4 and 5; in the case labeled
with an asterisk, also photometric information was used;
(7) Johnson B magnitude (from Tycho);
(8) Johnson V magnitude (from Tycho); and
(9) visual extinction AV from Strömgren or Johnson photometry
(Sect. 5.4).
We do not list photometric data for eight clear non-members
(Sect. 5.4). Membership for the run-away star 
Per
(HD 24912) comes down to semantics; we have indicated it by the label R.
