The Spacelab-1 Very Wide Field Survey of UV-excess objects. II - Analysis of 7 stars of various nature
Multiwavelength observations of seven stellar objects with strong UVexcesses are presented. The observations are IUE spectrophotometry,Stromgren Vuvby optical photometry, Johnson JHK infrared photometry,intermediate resolution optical spectroscopy, and in one case a CORAVELradial velocity survey. Three of the objects are field subdwarfs (one ofwhich is helium-rich) with z-distances of from -150 to -300 pc from thegalactic plane. A fourth subdwarf belongs to a binary system at z ofabout -500 pc; the primary of this system is a red giant. The threeother objects are normal gravity early-type stars which appear to belocated far below the galactic plane. One of them (CPD-61 deg 455) wouldappear to be a massive binary at z of about -5.8 kpc, and might providecritical clues concerning the nature of high latitude B stars if orbitalmotion is confirmed by future work.

| Four-colour and H beta photometry of southern B stars at high galactic latitudes
Four-color and H beta photometry has been obtained for 105 early-type HDstars with galactic latitudes less than -45 deg. They are mostly late Bstars of luminosity class V to III. Two new Am stars and several Ap orBp stars are detected photometrically. Absolute magnitudes aredetermined from the photometry and from MK types where available. Theinterstellar reddening of many of the more distant stars is very small,suggesting either the existence of undetected peculiar stars in thesample or that there are areas of effectively zero reddening at highsouthern galactic latitudes.
