Notes. Column 5: the B-band photometry of member ID#2,5 comes from the Tycho-2 Catalogue (Høg et al. 2000); the B-band photometry for member ID#10,11,12 is obtained with their V-band photometry and B − V colors (Lyo et al. 2008). Column 6: the V-band photometry of member ID#1, 6, 7, 8, 9 comes from Feigelson et al. (2003); the V-band photometry of member ID#2,5 comes from the Tycho-2 Catalogue (Høg et al. 2000); the V-band photometry of member ID#10,11,12 is obtained from its I-band photometry and V − I colors (Lyo et al. 2008). Column 7: the R-band photometry of member ID#1,6,7,8,9 comes from Feigelson et al. (2003), whereas the R-band photometry of member ID#10,11,12 is obtained with its I-band photometry and R − I colors from (Lyo et al. 2008). Column 8: the I-band photometry for member ID#1,6,7,8,9 comes from Feigelson et al. (2003), whereas the I-band photometry for member ID#10,11,12 is from the DENIS survey (Epchtein et al. 1997). Columns 9–11: the photometry for member ID#3,4,6,7 is from Grady et al. (2004). The photometry for other members comes from the 2MASS survey (Skrutskie et al. 2006).
