General Description

In this observing run the B components of two bright double star systems
 shall be observed. Weak absorption lines of the material of the mass losing main
 component shall be detected.
There are 4 OBs, 2 for each system, to get spectra with both blue cameras of UVES.
Acquisition takes place on the weaker B component in each case. The slit is rotated
 to the position angle of the binaries to eventually get spatial resolved spectra
 of the circumstellar matter. For alpha Herculis both components are located in the
 slit, while for BO Carinae the B component is located at one end of the slit to
 put the slit as near as possible to the main component.
