Appendix A: Target list

The following Tables A.1 to A.4 contain all targets we observed. The different columns contain the following parameters: Col. 1 the name of the target. Most names are either from the Henry Draper Catalog, the “Bonner Durchmusterung” or from Kun & Pasztor (1990). Column 2 and 3 give the right ascension and declination with equinox 2000. Column 4 shows the spectral type adapted in this work. In Col. 5 we list the separation of the detected companions up to a maximum separation of 3′′. Any companion further out is not shown. The position angle is shown in Col. 6. Column 7 presents the magnitude difference between primary and secondary. The membership of the target to the association is shown in Col. 8. The spectral types found in the literature are then given in Col. 9. The numbers in the table denote the following: 16: Roeser & Bastian (1988), 17: Simonson (1968), 18: Garrison (1970), 19: Contreras et al. (2002), 20: Morgan et al. (1955), 21: Blaauw et al. (1959), 22: Garrison & Kormendy (1976), 23: Walborn (1971), 24: Jaschek et al. (1964), 25: Sicilia-Aguilar et al. (2005), 26: Hiltner & Johnson (1956), 27: Melikian et al. (1988), 28: Skiff (2007), 29: Kharchenko (2001), 30: Garmany & Stencel (1992), 31: Morgan et al. (1953), 32: Mendoza V. (1958).
