Figure 4: Left: ratio of the actual number of matches between the X-ray source list and USNO-B catalog to the the expected number of chance coincidences, as a function of the search radius. Right: difference between the number of matches and the expected number of chance coincidences. The vertical dashed line in both panels shows the search radius of 3.6 arcsec. The shaded area indicates the Poisson uncertainty, computed from the square root of the actual number of matches. |

Figure 5:
The incompleteness-corrected XLF of HMXB candidates in
LMC. The upper histogram shows all sources from Table 3,
except two in the 30 Dor region; the lower one
shows likely HMXB candidates (upper part of Table 3).
These two histograms provide upper and lower
limits for the true HMXB XLF.
The upper grey line and shaded area show the luminosity distribution
predicted from the "universal'' XLF of Grimm et al. (2003) extrapolated
towards low luminosities and its uncertainty.
The lower solid and dashed lines show the same XLF modified by the
"propeller effect'' assuming the black hole fraction of

Figure 7: Distribution of spin periods ( left) and magnetic field strength ( right, Coburn et al. 2002) in high mass X-ray binaries. The spin period distributions are shown separately for the Milky Way (Liu et al. 2000) and SMC (Corbet et al. 2004) sources. The SMC distribution is shifted along the x axis by 0.2 dex for clarity. The smooth solid lines in both panels show the model distributions used for calculation of the propeller effect. |

Impact of the propeller effect on the luminosity distribution
of high mass X-ray binaries with a neutron star primary.
The straight line shows the initial power law
distribution with differential slope 1.6. The curved lines show the
luminosity function modified by the propeller effect for different
parameters of the distributions of the neutron star spin and magnetic
field. The neutron star mass and radius are
