Notes. Low-resolution quantitative and morphological classification from Mathys (1988) and from Walborn (Walborn 1972, 1973; Walborn et al. 2002) and Garrison et al. (1977, GHS), respectively; high-resolution quantitative classification from the present study together with morphological classification based on the original data (R = 48   000) and degraded ones (R = 4000). Additional information about vsini   (in km s-1 ; macroturbulence not accounted for) and binarity status of the stars is also provided. Binarity status from speckle interferometry (Mason et al. 2009) and spectroscopy (previous and present).


Results from the speckle interferometric survey of Mason et al. (2009): VD = visually double; VS = visually single object.


Spectroscopic binarity status: SS = spectroscopically single object; SB1/SB2 = single-/double-lined spectroscopic binary; SB1/2? = possible spectroscopic binary.
